I've recently updated IntelliJ to 2020.2 version. After that, In all of the projects I'm working with (java + maven), when I'm trying to build project (menu Build -> Build Project), I'm getting such log:
Executing pre-compile tasks...
Loading Ant Configuration...
Running Ant Tasks...
at index 8
Executing post-compile tasks...
Loading Ant Configuration...
Running Ant Tasks...
Synchronizing output directories...
30.07.2020 10:15 - Build completed with 1 error and 0 warnings in 942 ms
Build via maven works. Did anyone faced the same or similar problem? Any workarounds or magic flag to set?
I have also found stacktrace from exception:
