I looked at the instructions in github/readme.md, and I'm trying to run the child IDEA from kotlin root project.
I see an IDEA run configuration, but it has and X, and when I look at the run configuration I see the error: Class ‘com.intellij.idea.Main’ not found in module ‘idea_runner’.
Also, when I try to run “All Compiler Tests” I get a lot of compiler errors, e.g. all the com.intellij.psi imports.
Did I miss a step, or do I need to set some dependency I don’t know about? Thanks!
