I'm having issues with the new Idea X. I'm using Maven integration and have project B depending on project A. The code builds in Maven, it shows up Green in the editor, but when I try to Build->Make Project, I get compilation errors in project B saying it can't find classes defined in project A. The code definitely exists and I can control-click on any of the missing classes and it takes me to the classes in question in project A.
I've tried doing a Rebuild Project and a Maven -> Force Reimport, but still have the same errors. Anything else I can try, short of rebuilding all the indexes?
