I did some research on this topic and it seems that I have different problem from described around. IDEA ver 14.1.
I have project, that have 4 Git Roots. Project, Project-commons, Project-ui and Data Model. Due to certain config, I need to put commons, ui and Data Model into Project dir, but it resulted in Idea highlighting Project-commons, Project-ui and Data Model as red folders.
Git still works for me (as well as Maven), I didn't have any merge errors. What does that red highlight mean? Using "Synchronize" option to them helps, until I restart IDEA. I believe it has to do something with 3 Git roots inside another Git folder, but how do I fix it?
It looks like this:
Thank you in advance.
