To develop IntelliJ IDEA, you can use either IntelliJ IDEA Community Edition or IntelliJ IDEA Ultimate not older than 15.0. To build and run the code:
- Run getPlugins.sh / getPlugins.bat from the project root directory to check out additional modules.
- If this git repository is not on 'master' branch you need to checkout the same branches/tags in android and android/tools-base git repositories.
- Open the project.
- If an error notification about a missing required plugin (e.g. Kotlin) is shown enable or install that plugin.
- Configure a JSDK named "IDEA jdk" (case sensitive), pointing to an installation of JDK 1.6.
- Unless you're running on a Mac with an Apple JDK, add <JDK_HOME>/lib/tools.jar to the set of "IDEA jdk" jars.
- Configure a JSDK named "1.8", pointing to an installation of JDK 1.8.
- Add <JDK_18_HOME>/lib/tools.jar to the set of "1.8" jars.
- Use Build | Make Project to build the code.
- To run the code, use the provided shared run configuration "IDEA".
