Is there something I'm not taking into consideration? As far as I can tell the code should work ok.

Intellij plugin missing new questions
Is the IntelliJ plugin updated? I think I downloaded the updated one 3.27 but I still don't see any projects in the 2 new modules. Do I need to git pull something from somewhere I don't remember exactly if I needed to do anything else when I got this running the first time.
