IntelliJ IDEA 2019.3 Help

Supported compilers

Currently IntelliJ IDEA supports the following Java compilers:

  • javac

    This compiler is taken from the Java SDK currently assigned to the project.

  • Eclipse

    IntelliJ IDEA comes bundled with the Eclipse compiler.

  • Ajc

    This compiler is not included in IntelliJ IDEA distribution and should be downloaded separately.

    To use the compiler in IntelliJ IDEA, you also need to download, install, and enable the AspectJ Support plugin.

    The plugin is not bundled with IntelliJ IDEA, but it can be installed from the JetBrains plugin repository as described in Managing plugins.

Besides that, IntelliJ IDEA supports compilers for Flex, Groovy, Android DX. The corresponding plugins should be also downloaded, installed and enabled.
