I am using Ultimate 12.1.4 on a project using Maven and Git. Recently, I am unable to commit changes because IntelliJ hangs with a spinning box "Performing VCS Refresh".
I let it run for a looong time (over an hour) but it didn't finish.
I also tried invalidating caches and restarting. Didn't help.
What is going on and how can I fix/work around it?
