Why does my Intellij Git plugin not commit files once I click commit?

Question

Using IntelliJ 11.1.5, I was having trouble with committing my active changelist to my local Git repository. When I would try to commit, I would observe that though the dialog would come up, clicking commit did nothing, and I would need to play with various configurations of unnecessary subchangelists, committing one file at a time, or unchecking the "optimize imports" and "code analysis" in order to get it to work.

Please note, that this was a somewhat random occurrence, and at other times this wouldn't be an issue. In fact, when I switched to Git GUI or Git Bash the commits worked without incident.

So how do I fix things to be able to use the Git plugin?

Answer 1

I was experiencing problem with non-modal interface in version Ultimate 2020.3 and it turned-out I had to click on Commit button several time in order to work.

BTW, I've also did what @noisebelt suggested -> Invalidate Cache and Restart before switching to non-modal interface. To switch to that interface:

1. Go to File > Settings > Version Control > Commit (For Mac: IntelliJ IDEA > Preferences > Version Control > Commit)
2. Untick Use non-modal commit interface checkbox.
3. Good luck! :)

UPDATE: You might want to un-check some of checkboxes in Settings>Version Control>Commit under "Before Commit" section such as Reformat Code, Rearrange Code, etc. and by doing that diagnose what might be causing this issue with committing.
