Work offline
A lot of features in MPS require access to the Internet. If you are working offline (for example, in an isolated environment), there are some aspects that you should keep in mind.
If you don't have internet access to view the online help, you can use the MPS Help plugin, which serves the help pages via the built-in web server for offline use.
note
The offline help plugin is updated when a new major version is released. Changes that are added to online help during the release cycle may not be available in the offline help.
By default, MPS is configured to check for updates automatically and notify you when a new version is available.
If MPS does not have HTTP access outside your local network, it will not be able to check for updates and apply patches. In this case, you have to download new versions of the IDE and install them manually as described in Standalone installation.
note
Without internet access, you can't install MPS using the Toolbox App.
For more information, refer to Update MPS.
Usually, plugins are installed from JetBrains Marketplace. However, you can set up a custom plugin repository in your local network and configure MPS to use it for installing and updating plugins.
Alternatively, you can download and manually install plugins from disk.
Most likely, your source code is under some sort of version control system (VCS). If a remote repository is not in your local network, and there is no internet access, MPS will not be able to communicate with the VCS. For example, if you are using Git, you will be able to commit your changes but won’t be able to push them to the remote repository or pull updates from it.
For more information about VCS integration, refer to Version control.
When you run MPS for the first time, you are prompted whether to send anonymous data on the features and plugins you use, your hardware and software configuration, file types, number of files per project, and so on. This does not include any personal or sensitive data, such as parts of your source code or file names. This information is collected in accordance with the JetBrains Privacy Policy and is used to help improve the products and overall experience.
Even if you enable anonymous usage statistics, it will not be sent if there is no HTTP access outside your local network. Also, you can disable this feature entirely if you agreed at first and then changed your mind later.
In the Settings dialog (CtrlAlt0S) , select Appearance & Behavior | System Settings | Data Sharing.
Clear the Send usage statistics checkbox.
