This Bugzilla instance is a read-only archive of historic NetBeans bug reports. To report a bug in NetBeans please follow the project's instructions for reporting issues.
Every command of version control (I'm using git) chosen from the menus makes netbeans hang and I need to kill the process. I have reinstalled netbeans from the same version of archive on my notebook and have updated to the version (Build 201705191307) so they are exactly the same, though my notebook doesn't exhibit this behavior at all (OS'es are the same as well, Kubuntu 17.04 fully updated). Be it 'Push...' or 'Pull...', 'Commit...', they all make netbeans hang. I connect to my own git server, which is localhost on the machine that makes netbeans hang, externally via internet on the other. When i change the localhost machine's git config to also go via the router's external interface, it doesn't resolve the issue, and I can't think of anything else.
I just noticed it doesn't happen when i choose 'Push...' this time, but it does hang when I choose "Commit...", regardless if there were any changes or not. Also, when I double-click the title bar or otherwise resize the main windowframe, everything redraws properly, I just never regain control over the application itself. Another thing: performing the update in a terminal works properly and as expected, restarting netbeans shows the changes have taken effect also as expected (file no longer marked as ahead of repository).
I had the same issue in the same build, but in Windows. Git was totally unresponsive, cannot push, pull, commit, add... check revisions was always loading... I tried reinstalling without success. Finally, I installed git for windows and did add, commit, push operations through command line. After restarting netbeans, it was working again :)
