SonarQube plug-in cannot unzip a file from the cache

Today I started seeing intermittent, but frequent, problem with the sonar qube plug-in in my builds, where one of the zipfiles seems to be missing or corrupted. Is there any chance to know what is going on? Thanks!

And this is a job example where it fails:
