How To...

Install Non-Bundled Version of Java

TeamCity Server requires a Java SE JRE installation to run. A compatible JRE version is bundled in the TeamCity .exe installer but needs to be installed separately when using other distributions.

TeamCity selects the Java version to run the server process as follows:

• By default, if your TeamCity installation has a bundled JRE (the <TeamCity Home>\jre directory exists), it will be used to run the TeamCity server process. To use a different JRE, specify its path via the TEAMCITY_JRE environment variable.

• If there is no <TeamCity Home>\jre directory present, TeamCity looks for the JRE_HOME or JAVA_HOME environment variable pointing to the installation directory of JRE or JVM (Java SDK) respectively. If both variables are declared, JRE will be used.

The necessary steps to update the Java installation depend on the distribution used.

If your TeamCity installation has a bundled JRE (there is the <TeamCity Home>\jre directory), update it by installing a newer JRE per installation instructions and copying the content of the resulting directory to replace the content of the existing <TeamCity Home>\jre directory.
If you also run a TeamCity agent from the <TeamCity Home>\buildAgent directory, install JDK (Java SDK) installation instead of JRE and copy the content of the JDK installation directory into <TeamCity Home>\jre.

Update from 32-bit to 64-bit Java

TeamCity server is bundled with the 64-bit JVM but can run under both 32- and 64-bit versions.

If you need to update 32-bit Java to 64-bit JVM, note that the memory usage is almost doubled when switching from 32- to 64-bit. Make sure to specify at least twice as much memory as for 32-bit JVM. Read how to change memory settings.

To update to 64-bit Java, either use the bundled version of Java or:

1. Update Java to be used by the server.

2. Set JVM memory options. It is recommended to set the -Xmx4g option for 64-bit JVM.

Install Non-Bundled Version of Tomcat

The TeamCity Server distributions include a Tomcat version tested to work fine with the current version. You can use an alternative Tomcat version, but note that other combinations are not guaranteed to work correctly.

To use another version of the Tomcat web server instead of the bundled one, you need to perform the Tomcat upgrade/patch.

When upgrading the version of Tomcat to be used by TeamCity, we suggest that you:

• Back up the current TeamCity Home.

• Delete/move from the TeamCity Home directories that are also present in the Tomcat distribution.

• Unpack the Tomcat distribution to the TeamCity Home directory.

• Copy TeamCity-specific files from the previously backed-up/moved directories to the TeamCity Home:

  • files under bin which are not present in the Tomcat distribution

  • review differences between the default Tomcat conf directory and one from TeamCity, update Tomcat files with TeamCity-specific settings (teamcity-* files, and portions of server.xml)

  • delete the default Tomcat webapps/ROOT directory and replace it with the one provided by TeamCity

Autostart TeamCity Server on macOS

Starting up the TeamCity server on macOS is quite similar to starting Tomcat on macOS.

1. Install TeamCity and make sure it works if started from the command line with bin/teamcity-server.sh start. This instruction assumes that TeamCity is installed to /Library/TeamCity.

2. Create the /Library/LaunchDaemons/jetbrains.teamcity.server.plist file with the following content:

   <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>WorkingDirectory</key> <string>/Library/TeamCity</string> <key>Debug</key> <false/> <key>Label</key> <string>jetbrains.teamcity.server</string> <key>OnDemand</key> <false/> <key>KeepAlive</key> <true/> <key>ProgramArguments</key> <array> <string>/bin/bash</string> <string>--login</string> <string>-c</string> <string>bin/teamcity-server.sh run</string> </array> <key>RunAtLoad</key> <true/> <key>StandardErrorPath</key> <string>logs/launchd.err.log</string> <key>StandardOutPath</key> <string>logs/launchd.out.log</string> </dict> </plist>

3. Test your file by running:

   launchctl load /Library/LaunchDaemons/jetbrains.teamcity.server.plist

   This command should start the TeamCity server (you can see this from logs/teamcity-server.log and in your browser).

4. If you don't want TeamCity to start under the root permissions, specify the UserName key in the .plist file, for example:

   <key>UserName</key> <string>teamcity_user</string>

The TeamCity server will now start automatically when the machine starts. To configure automatic start of a TeamCity build agent, see the dedicated section.

Automate TeamCity Server Installation

For an automated TeamCity server installation, use the .tar.gz distribution.

Typically, you will need to unpack it and make the script perform the steps noted in this section.

If you want to get a preconfigured server right away, put the files from a previously configured server into the Data Directory. For each new server, you will need to:

• ensure it points to a new database (configured in <Data Directory>\config\database.properties);

• change the <Data Directory>\config\main-config.xml file not to have the uuid attribute in the root XML element (so the new one can be generated); set the appropriate value for the rootURL attribute.

Retrieve Administrator Password

On the first start with the empty database, TeamCity displays the Administrator Setup page which allows creating a user with full administrative permissions (assigning the System Administrator role).

If you want to regain access to the system and you cannot log in as a user with the System Administrator role, you can log in as a super user and change the existing administrator account password or create a new account with the System Administrator role.

It is also possible to use REST API to add the System Administrator role to any existing user.

If you use built-in authentication and have correct email specified, you can reset the password from the login page.

Setup TeamCity in Replication/Clustering Environment

It is possible to add a secondary TeamCity node to ensure high availability and offload some operations from the main server. All nodes need to be connected to the same TeamCity Data Directory and the database.

To address fast disaster recovery scenarios, TeamCity supports active - failover (cold standby) approach: the data that the TeamCity server uses can be replicated and a solution put in place to start a new server using the same data if the currently active server malfunctions.

As to the data, the TeamCity server uses both database and file storage (Data Directory). You can browse through TeamCity Data Backup and TeamCity Data Directory pages in to get more information on TeamCity data storing. Basically, both the TeamCity Data Directory on the disk and the database which TeamCity uses must remain in a consistent state and thus must be replicated together.
Only a single TeamCity server instance should use the database and Data Directory at any time.

Ensure that the distribution of the TeamCity failover/backup server is of exactly the same version as the main server. It is also important to ensure the same server environment/startup options like memory settings, and so on.

TeamCity agents farm can be reused between the main and the failover servers. Agents will automatically connect to the new server if you make the failover server to be resolved via the old server DNS name and agents connect to the server using the DNS name. See also information on switching from one server to another.
If appropriate, the agents can be replicated just as the server. However, there is no need to replicate any TeamCity-specific data on the agents except for the conf\buildAgent.properties file as all the rest of the data can typically be renewed from the server. In case of replicated agents farm, the replica agents just need to be connected to the failover server.

In case of two servers installations for redundancy purposes, they can use the same set of licenses as only one of them is running at any given moment.

Estimate Number of Required Build Agents

The number of required build agents depends on the server usage pattern, type of builds, team size, commitment of the team to CI process, and so on. In general, the best way is to start with three agents and see how they handle the projects on your server, and then make estimations for the future.

You might want to increase the number of agents when you see:

• builds waiting for an idle agent in the build queue;

• more changes included into each build than you find comfortable (for example, for build failures analysis);

• necessity for different environments.

We've seen patterns of having an agent per each 20 build configurations (types of builds). Or a build agent per 1-2 developers.

TeamCity Security Notes

The contents of this section have been moved to the dedicated article.

Configure Newly Installed MySQL Server

If MySQL server is going to be used with TeamCity in addition to the basic setup, you should review and probably change some of the MySQL server settings. If MySQL is installed on Windows, the settings are located in my.ini file which usually can be found under MySQL installation directory. For Unix-like systems the file is called my.cnf and can be placed somewhere under /etc directory. Read more about configuration file location in MySQL documentation. Note: you'll need to restart MySQL server after changing settings in my.ini|my.cnf.

The following settings should be reviewed and/or changed:

Configure Newly Installed PostgreSQL Server

For better TeamCity server performance, it is recommended to change some of the parameters of the newly installed PostgreSQL server. You can read more about PostgreSQL performance optimization in PostgreSQL Wiki.

The parameters below can be changed in the postgresql.conf file located in the in PostgreSQL's data directory.

Set Up TeamCity behind a Proxy Server

The contents of this section have been moved to the dedicated article.

Enforce hiding stacktrace

If a user with access to your TeamCity server submits an invalid cross-site scripting (XSS) payload, the server will display the "Unexpected error" page containing a related stacktrace. To prevent exposing any sensible information about your environment via this stacktrace, you might want to disable its display. For this, set the teamcity.web.runtimeError.showStacktrace internal property to false.

Configure HTTPS for TeamCity Web UI

TeamCity now allows configuring HTTPS access easily. However, for large public facing TeamCity installations, it is still recommended that you set up a reverse proxy like NGINX or Apache in front of TeamCity that would handle HTTPS and use HTTP TeamCity server port as the upstream.

HTTPS-related configuration of the proxy is not specific for TeamCity and is generic as for any web application. Make sure to configure the reverse proxy per our recommendations. Generic web application best practices apply (like disabling http access to TeamCity at all).

For small servers, you can set up HTTPS via the internal Tomcat means, but this is not recommended as it may significantly increase the CPU load.

For configuring clients to access TeamCity server via HTTPS while using self-signed certificate, check the related instructions.

Configure TeamCity to Use Proxy Server for Outgoing Connections

The contents of this section have been moved to the dedicated article.

Configure TeamCity Agent to Use Proxy To Connect to TeamCity Server

This section covers the configuration of a proxy server for TeamCity agent-to-server connections.

On the TeamCity agent side, specify the proxy to connect to TeamCity server using the following properties in the buildAgent.properties file:

Note that the proxy has to be configured not to cache any TeamCity server responses; for example, if you use Squid, add "cache deny all" line to the squid.conf file.

Install Multiple Agents on the Same Machine

See the corresponding section under agent installation documentation.

Change Server Port

See corresponding section in server installation instructions.

Test-drive Newer TeamCity Version before Upgrade

It's advised to try a new TeamCity version before upgrading your production server. The usual procedure is to create a copy of your production TeamCity installation, then upgrade it, try the things out, and, when everything is checked, drop the test server and upgrade the main one. When you start the test server, remember to change the Server URL, disable the email notifier as well as other features on the new server.

Create a Copy of TeamCity Server with All Data

In case you want to preserve the original server as well as the copy, make sure to check the licensing considerations.

Move TeamCity Projects from One Server to Another

If you need to move data to a fresh server without existing data, it is recommended to move the server or copy it and then delete the data which is not necessary on the new server.

If you need to join the data with already existing data on the new server, there is a dedicated feature to move projects with most of the associated data from one server to another: Projects Import.

Here are some notes on manual move of the settings in case you ever want to perform it

It is possible to move settings of a project or a build configuration to another server with simple file copying.

The two TeamCity servers (source and target) should be of exactly the same version (same build).

All the identifiers throughout all the projects, build configurations and VCS roots of both servers should be unique. If they are not, you can change them via web UI. If entities with the same id are present on different servers, the entities are assumed to be the same. For example this is useful for having global set of VCS roots on all the servers.

To move settings of the project and all its build configuration from one server to another:

From the TeamCity Data Directory, copy the directories of corresponding projects (.BuildServer\config\projects\<id>) and all its parent projects to .BuildServer\config\projects of the target server. This moves project settings, build configuration settings, VCS roots defined in the projects preserving the links between them. If there are same-named files on the target server as those copied, this can happen in case of a) id match: same entities already exist on the target server, in which case the clashing files can be excluded from copying, or b) id clash: different entities happen to have same ids. In this case it should be resolved either by changing entity ID on the source or target server to fulfill the uniqueness requirement.

The set of parent projects is to be identified manually based on the web UI or the directory names on disk (which be default will have the same prefix).

Note: It might make sense to keep the settings of the root project synchronized between all the servers (by synchronizing content of .BuildServer\config\projects_Root directory). For example, this will ensure same settings for the default clean-up policy on all the servers.

Further steps after projects copying might be:

• delete unused data in the copied parent projects (if any) on the target server

• use "server health" reports to identify duplicate VCS roots appeared in result of copying, if any

• archive the projects on the source server and adjust clean-up rules (to be able to see build's history, if necessary)

What is not copied by the approach above:

• pausing comment and user of the paused build configurations

• archiving user of the archived projects

• global server settings (for example, Maven settings.xml profiles, tools like handle.exe, external change viewers, build queue priorities, issue trackers). These are stored under various files under .BuildServer\config directory and should be synchronized either on the file level or by configuring the same settings in the server administration UI.

• project association with agent pools

• templates from other projects which are not parents of the copied one. This configuration is actually deprecated in TeamCity 8.0 and is only supported as legacy. Templates used in several projects should be moved to the common parent project or root project.

• no data configured for the agents (build configurations that are allowed to run on the agent).

• no user-related or user group-related settings (like roles and notification rules)

• no state-related data like mutes and investigations.

Move TeamCity Installation to a New Machine

If you need to move an existing TeamCity installation to new hardware or a clean OS, you can install the same TeamCity version on the new machine, stop the old server, connect the new server to the same TeamCity Data Directory and make sure the server uses the same environment. Alternatively, you can follow the instructions on copying the server from one machine to another.

After the move, make the clients use the new server address, if changed.

You can use the existing license keys when you move the server from one machine to another (as long as there are no two servers running at the same time). As license keys are stored under <TeamCity Data Directory>, you transfer the license keys with all the other TeamCity settings data.

It is usually advised not to combine TeamCity update with any other actions, like environment or hardware changes, and perform the changes one at a time so that, if something goes wrong, the cause can be easily tracked.

Move TeamCity Agent to a New Machine

Apart from the binaries, TeamCity agent installation stores its configuration and data left from the builds it run. Usually the data from the previous builds makes preparation for the future builds a bit faster, but it can be deleted if necessary. The configuration is stored under conf and launcher\conf directories. The data collected by previous build is stored under work and system directories.

The simplest way to move agent installation into a new machine or new location is to:

• stop existing agent

• install a new agent on the new machine

• copy conf/buildAgent.properties from the old installation to a new one

• start the new agent. With these steps the agent will be recognized by TeamCity server as the same and will perform clean checkout for all the builds.

Please also review the section for a list of directories that can be deleted without affecting builds consistency.

Share the Build number for Builds in a Chain Build

A build number can be shared for builds connected by a snapshot dependency or an artifact dependency using a reference to the following dependency property: %dep.<btID>.system.build.number%.

For example, you have build configurations A and B that you want to build in sync: use the same sources and take the same build number.
Do the following:

1. Create build configuration C, then snapshot dependencies: A on C and B on C.

2. Set the Build number format in A and B to:

Where <btID> is the ID of the build configuration C. The approach works best when builds reuse is turned off via the Snapshot Dependencies snapshot dependency option set to off.

Read more about dependency properties.

Please watch/comment the issue related to sharing a build number TW-7745.

Make Temporary Build Files Erased between the Builds

Update your build script to use path stored in ${teamcity.build.tempDir} (Ant's style name) property as the temp directory. TeamCity agent creates the directory before the build and deletes it right after the build.

Clear Build Queue if It Has Too Many Builds due to a Configuration Error

Try pausing the build configuration that has the builds queued. On build configuration pausing all its builds are removed form the queue.
Also there is an ability to delete many builds from the build queue in a single dialog.

Automatically create or change TeamCity build configuration settings

If you need a level of automation and web administration UI does not suite your needs, there several possibilities:

• use REST API

• change configuration files directly on disk (see more at <TeamCity Data Directory>)

• write a TeamCity Java plugin that will perform the tasks using open API.

Attach Cucumber Reporter to Ant Build

If you use Cucumber for Java applications testing you should run cucumber with --expand and special --format options. More over you should specify RUBYLIB environment variable pointing on necessary TeamCity Rake Runner ruby scripts:

Please check the RUBYLIB path separator (';' for Windows, ':' for Linux, or '${path.separator}' in ant for safety).
If you are launching Cucumber tests using the Rake build language, TeamCity will add all necessary command line parameters and environment variables automatically. This tip works in TeamCity version >= 5.0.

Get Last Successful Build Number

Use URL like this:

The build number will be returned as a plain-text response.
For <ID of build configuration>, see Identifier.
This functionality is provided by REST API

Set up Deployment for My Application in TeamCity

TeamCity has enough features to handle orchestration part of the deployments with the actual deployment logic configured in the build script / build runner. TeamCity supports a variety of generic build tools, so any specific tool can be run from within TeamCity. To ease specific tool usage, it is possible to wrap it into a meta-runner or write a custom plugin for that.

In general, setup steps for configuring deployments are:

1. Write a build script that will perform the deployment task for the binary files available on the disk. (e.g. use Ant or MSBuild for this. For typical deployment transports use Deployer runners). See also Integrate with Build and Reporting Tools. You can use Meta-Runner to reuse a script with convenient UI.

2. Create a build configuration in TeamCity that will execute the build script and perform the actual deployment. If the deployment is to be visible or startable only by the limited set of users, place the build configuration in a separate TeamCity project and make sure the users have appropriate permissions in the project.

3. In this build configuration configure artifact dependency on a build configuration that produces binaries that need to be deployed.

4. Configure one of the available triggers in the deploying build configuration if you need the deployment to be triggered automatically (e.g. to deploy last successful of last pinned build), or use "Promote" action in the build that produced the binaries to be deployed.

5. Consider using snapshot dependencies in addition to artifact ones and check Build Chains tab to get the overview of the builds. In this case artifact dependency should use "Build from the same chain" option.

6. If you need to parametrize the deployment (e.g. specify different target machines in different runs), pass parameters to the build script using custom build run dialog. Consider using Typed Parameters to make the custom run dialog easier to use or handle passwords.

7. If the deploying build is triggered manually consider also adding commands in the build script to pin and tag the build being deployed (via sending a REST API request). You can also use a build number from the build that generated the artifact.

Further recommendations:

• Setup a separate build configurations for each target environment

• Use build's Dependencies tab for navigation between build producing the binaries and deploying builds/tasks

• If necessary, use parameter with "prompt" display mode to ask for "confirmation" on running a build

• Change title of the build configuration "Run" button

Use an External Tool that My Build Relies on

If you need to use specific external tool to be installed on a build agent to run your builds, you have the following options:

• Install and register the tool in TeamCity:

  1. Install the tool on all the agents that will run the build. This can be done manually or via an automated script. For simple file distribution also see Installing Agent Tools

  2. Add a property into buildAgent.properties file (or add environment variable to the system) with the tool home location as the value.

  3. Add agent requirement for the property in the build configuration.

  4. Use the property in the build script.

• Check in the tool into the version control and use relative paths.

• Add environment preparation stage into the build script to get the tool form elsewhere.

• Create a separate build configuration with a single "fake" build which would contain required files as artifacts, then use artifact dependencies to send files to the target build.

Integrate with Build and Reporting Tools

If you have a build tool or a tool that generates some report/provides code metrics which is not yet supported by TeamCity or any of the plugins, most probably you can use it in TeamCity even without dedicated integration.

The integration tasks involved are collecting the data in the scope of a build and then reporting the data to TeamCity so that they can be presented in the build results or in other ways.

Data collection

The easiest way for a start is to modify your build scripts to make use of the selected tool and collect all the required data.
If you can run the tool from a command line console, then you can run it in TeamCity with a command line runner. This will give you detection of the messages printed into standard error output. The build can be marked as failed is the exit code is not zero or there is output to standard error via build failure condition.
If the tool has launchers for any of the supported build scripting engines like Ant, Maven or MSBuild, then you can use corresponding runner in TeamCity to start the tool. See also Use an External Tool that My Build Relies on for the recommendations on how to run an external tool.

You can also consider creating a Meta Runner to let the tool have dedicated UI in TeamCity.

For an advanced integration a custom TeamCity plugin can be developed in Java to ease tool configuration and running.

Presenting data in TeamCity

The build progress can be reported to TeamCity via service messages and build status text can also be updated.

For testing tools, if they are not yet supported you can report tests progress to TeamCity from the build via test-related service messages or generate one of the supported XML reports in the build and let it be imported via a service message of configured XML Report Processing build feature.

To present the results for a generic report, the approach might be to generate HTML report in the build script, pack it into archive and publish as a build artifact. Then configure a report tab to display the HTML report as a tab on build's results.

A metrics value can be published as TeamCity statistics via service message and then displayed in a custom chart. You can also configure build failure condition based on the metric.

If the tool reports code-attributing information like Inspections or Duplicates, TeamCity-bundled report can be used to display the results. A custom plugin will be necessary to process the tool-specific report into TeamCity-specific data model. Example of this can be found in XML Test Reporting plugin and FXCop plugin (see a link on the Bundled Open-Source Plugins page).

See also Import coverage results in TeamCity.

For advanced integration, a custom plugin will be necessary to store and present the data as required. See Developing TeamCity Plugins for more information on plugin development.

Restore Just Deleted Project

TeamCity moves deleted projects settings directories (which are named after the project id) to <TeamCity Data Directory>/config/_trash directory adding "<internal ID>" suffix to the directories.

To restore a project, find the project directory in the _trash directory and move it into regular projects settings directory: <TeamCity Data Directory>/config/projects while removing the ".projectN" suffix from the directory name.
You can do this while server is running, it should pick up the restored project automatically.

Note that TeamCity preserves builds history and other data stored in the database for deleted projects/build configurations for 5 days after the deletion time. All the associated data (builds and test history, changes, etc.) is removed during the next clean-up after the configurable (5 days by default) timeout elapses.

The config/_trash directory is not cleaned automatically and can be emptied manually if you are sure you do not need the deleted projects. No server restart is required.

Transfer 3 Default Agents to Another Server

This is not possible.

Each TeamCity server (Professional and Enterprise) allows using 3 or more agents bound to the server without any agent licenses. In case of the Professional server, by default 3 agents are bound to the server instance: users do not pay for these agents, there is no license key for them.
In case of the Enterprise server, the number of agents depends on your package and the agents are bound to the server license key.

So, the agents bound to the server cannot be transferred to another server.

If you need more build agents that are included with your TeamCity server, you can purchase additional build agent licenses and connect more agents in addition to those that come bound with the server.

See more on licensing.

Recover from "Data format of the Data Directory (NNN) and the database (MMM) do not match" error

If you get "Data format of the Data Directory (NNN) and the database (MMM) do not match." error on starting TeamCity, it means either the database or the TeamCity Data Directory were recently changed to an inconsistent state so they cannot be used together. Double-check the database and Data Directory locations and change them if they are not those where the server used to store the data.

If they are right, most probably it means that the server was upgraded with another database or Data Directory and the consistent upgrade requirement was not met for your main Data Directory and the database.

To recover from the state you will need backup of the consistent state made prior to the upgrade. You will need to restore that backup, ensure the right locations are used for the Data Directory and the database and perform the TeamCity upgrade.

Debug a Build on a Specific Agent

In case a build fails on some agent, it is possible to debug it on this very agent to investigate agent-specific issues. Do the following:

1. Go to the Agents page in the TeamCity web UI and select the agent.

2. Disable the agent to temporarily remove it from the build grid. Add a comment (optional). To enable the agent automatically after a certain time period, check the corresponding box and specify the time.

3. Select the build to debug.

4. Open the Custom Run dialog and specify the following options: a. In the Agent drop-down menu, select the disabled agent. b. It is recommended to select the run as Personal Build option to avoid intersection with regular builds.

5. When debugging is complete, enable the agent manually if automatic reenabling has not been configured.

You can also perform remote debugging of tests on an agent via the IntelliJ IDEA plugin for TeamCity.

Debug a Part of the Build (a build step)

If a build containing several steps fails at a certain step, it is possible to debug the step that breaks. Do the following:

1. Go to the build configuration and disable the build steps up to the one you want to debug.

2. Select the build to debug.

3. Open the Custom Run dialog and select the put the build to the queue top to give you build the priority.

4. When debugging is complete, reenable the build steps.

Watch Several TeamCity Servers with Windows Tray Notifier

TeamCity Tray Notifier is used normally to watch builds and receive notifications from a single TeamCity server. However, if you have more than one TeamCity server and want to monitor them with Windows Tray Notifier simultaneously, you need to start a separate instance of Tray Notifier for each of the servers from the command line with the /allowMultiple option:

• From the TeamCity Tray Notifier installation directory (by default, it's C:\Program Files\JetBrains\TeamCity) run the following command:

Optionally, for each of the Tray Notifier instances you can explicitly specify the URL of the server to connect using the /server option. Otherwise, for each further tray notifier instance you will need to log out and change the server's URL via the UI.

See also details in the issue tracker.
