Git (JetBrains)

Last modified: 20 April 2023

This page contains description of the fields and options available when setting up VCS roots using the Git Version Control System. The VCS is visible as "Git (JetBrains)" in VCS chooser to eliminate confusion with third-party plugin if third-party plugin is installed and as "Git" otherwise.

General Settings



The following protocols are supported for the server-side VCS Checkout Mode:

  • ssh: (e.g. ssh://git.somwhere.org/repos/test.git, ssh://git@git.somwhereElse.org/repos/test.git, scp-like syntax: git@git.somwhere.org:repos/test.git)

    note

    Scp-like syntax requires a colon after hostname, while usual ssh url does not. This is a common source of errors.

  • git: (e.g. git://git.kernel.org/pub/scm/git/git.git)

  • http: (e.g. http://git.somewhere.org/projects/test.git)

  • file: (e.g. file:///c:/projects/myproject/.git)

    note

    When you run TeamCity as a Windows service it cannot access a mapped network drives and repositories located on them.

Authentication Settings



Agent Settings



Please note that agent-side checkout has limited support for SSH. The only supported authentication method is "Default Private Key". Also you should set "StrictHostKeyChecking" to "no" in <USER_HOME>\.ssh\config, or add keys of remote hosts to the Known-Hosts database manually. If you plan to use VCS Checkout Mode, you need to have Git 1.6.4.0 (or higher) installed on the agents.

Supported default installation locations:

  • Windows (git.exe)

    • C:\Program Files\Git\bin

    • C:\Program Files (x86)\Git\bin

    • C:\cygwin\bin

  • Unix (git)

    • /usr/local/bin

    • /usr/bin

    • /opt/local/bin

    • /opt/bin

Internal Properties



For Git VCS it is possible to configure the following Configuring TeamCity Server Startup Properties:

Build Agent Configuration for Git:

Limitations



  • When using checkout on agent, limited subset of checkout rules is supported, because Git cannot clone a subdirectory of repository. You can only map whole repository to a specific directory using following checkout rule +:.=>subdir. The rest checkout rules are not supported.

Known Issues



  • Tagging is not supported over HTTP protocol

  • java.lang.OutOfMemoryError while fetch repository. Usually happens when there are big files in repository. By default TeamCity run fetch in a separate process, to run fetch in the server process set Configuring TeamCity Server Startup Properties teamcity.git.fetch.separate.process to false.

  • Git commits are sorted by their commiter times, not their child-parent relationships. This can cause incorrect order of commits and clean checkouts on agents (e.g. TW-13846). The current workaround is to synchronize time on a machines which push to repository tracked by TeamCity.

  • Teamcity ran as a Windows service cannot access a network mapped drives, so you cannot work with git repositories located on such drives. To make this work run TeamCity using teamcity-server.bat.

  • checkout on agent using ssh protocol can be slow due to java SSH implementation (see TW-14598 for details). To use native SSH implementation set teamcity.git.use.native.ssh to true.

  • inflation using streams in JGit prevents OutOfMemoryError but can be time consuming (see related thread at jgit-dev for details and TW-14947 issue related to the problem). If you meet conditions similar to described in the issue - try to increase teamcity.git.stream.file.threshold.mb. Additionally it is recommended to increase overall amount of memory dedicated for TeamCity to prevent OutOfMemoryError.

Development Links



Git support is implemented as an open-source plugin. For development links refer to the Git.
