How to add Kotlin PSI source files to IDEA Plugin project configuration

Question

I am trying to add support for kotlin for one of the IDEA plugins.

So far, I found this page and understood that I need to work with kotlin PSI files, such as KtCl

Answer 1

Those source files belongs to the Kotlin plugin, which is not strictly a part of IntelliJ IDEA distribution. You need to add the Kotlin plugin source to the project as well as the IDEA source.

There're two modules needed:

• https://github.com/JetBrains/kotlin/tree/master/idea
• https://github.com/JetBrains/kotlin/tree/master/compiler/psi/src/org/jetbrains/kotlin
