Hi, I'm getting as issue using scoverage sbt plugin.

When running on Jenkins sometimes is going on error as OutOfMemoryException:

Hi @albertoadami looking at your stacktrace I don't believe this has anything to do with scoverage. It's actually the Scalastyle plugin that seems to be throwing the error. I'd recommend opening this there.
