Show HN: A compile testing library for Kotlin

I recently released this compile testing library for Kotlin in the spirit of Google's [compile-testing](https://github.com/google/compile-testing). It can be used to test annotation processors, compiler plugins and code generation.

Features:

- Mixed-source sets: Compile Kotlin and Java source files together

- Supports compiler plugins

- Run annotation processors on Kotlin and Java sources

- Generate Kotlin and Java sources

- Provide your own instances of annotation processors directly to the compiler instead of letting the compiler create them with a service locator

- Debug annotation processors: Since the compilation runs in the same process as your application, you can easily debug it instead of having to attach your IDE's debugger manually to the compilation process

- Inherit classpath: Compiled sources have access to classes in your application

- Project Jigsaw compatible: Works with JDK 8 as well as JDK 9 and later

- JDK cross compilation: Provide your own JDK to compile the code against, instead of using the host application's JDK. This allows you to easily test your code on all JDK versions

- Find dependencies automatically on the host classpath

Hopefully it will be as helpful to you as it was to me.
