IntelliJ IDEA 2019.3 Help

Compile and build

Build process includes the following steps:

  • Compiling source code in the source path of a module and placing results to the output path.

  • Compiling source code in the test path of a module and placing results to the test output path.

  • Creating copies of the resource files in the output path.

  • Reporting problems in the Messages tool window.

With IntelliJ IDEA you can build your applications using Ant, Maven, Gradle, or the native IntelliJ IDEA builder.
