_remote.repositories FileLockInterruptionException NB 12.0

[Peter Ream <to...@gmail.com>]

I'm having a problem on Netbeans 12.0 using maven. I have an internal class
Icontils that I use in several projects. Everytime I try to delete or move
a project with this dependency, I get the error below. If I do the move or
delete from Netbeans 11.3, no problem. I am using maven bundled with both.
I have maven 3.6.1 installed and tried it. Works on 11.3, but not on 12.0.
The permissions for _remote.repositories look fine.

Mac OSX 10.15.6.
