Problems with integrating in latest IntelligeJ

[klaaslusterbroodvan]

Tried to use this, but it simply does not seem to be compatible.

This project is either outdated or the instructions fall short on how and where exactly to put in the repository and dependency lines. I tried several versions but it does not work with current IDEA:
