IntelliJ IDEA Community Edition & IntelliJ Platform
These instructions will help you build IntelliJ IDEA Community Edition from source code, which is the basis for IntelliJ Platform development. The following conventions will be used to refer to directories on your machine: *is your home directory. * is the root directory for the IntelliJ source code.
IntelliJ IDEA Community Edition source code is available from
github.com/JetBrains/intellij-communityby either cloning or downloading a zip file (based on a branch) into . The default is the master branch.
The master branch contains the source code which will be used to create the next major version of IntelliJ IDEA. The branch names and build numbers for older releases of IntelliJ IDEA can be found on the page of Build Number Ranges.
Speed Tip: If the complete repository history isn't needed then using a shallow clone (
git clone --depth 1) will save significant time.
These Git operations can also be done through the IntelliJ IDEA user interface.
IntelliJ IDEA Community Edition requires additional Android modules from separate Git repositories. To clone these repositories, run one of the
getPluginsscripts located in the directory. These scripts clone their respective master branches. *
getPlugins.shfor Linux or macOS. *
androidGit repositories to the same branches/tags.
Version 2020.1 or newer of IntelliJ IDEA Community Edition or IntelliJ IDEA Ultimate Edition is required to build and develop for the IntelliJ Platform.
Using IntelliJ IDEA File | Open, select thedirectory. * If IntelliJ IDEA displays an error about a missing or out of date required plugin (e.g. Kotlin), enable, upgrade, or install that plugin and restart IntelliJ IDEA. * If IntelliJ IDEA displays an error about a Gradle configuration not found, refresh the Gradle projects.
Speed Tip: If you have enough RAM on your computer, configure the compiler settings to enable the "Compile independent modules in parallel" option. Also, increase build process heap size:
These changes will greatly reduce compilation time.
To build IntelliJ IDEA Community Edition from source, choose Build | Build Project from the main menu.
To build installation packages, run the
antcommand in directory. See the
build.xmlfile for details.
To run the IntelliJ IDEA built from source, choose Run | Run from the main menu. This will use the preconfigured run configuration "IDEA".
To run tests on the build, apply these setting to the Run | Edit Configurations... | Templates | JUnit configuration tab: * Working dir:
