Issue when pushing to upstream branch due to OverlappingFileLockException about sbt-sonar

[joshserrin]

I'm running into the same issue. My sbt project has 18 subprojects and is running in gitlab-ci. I only get this exception on 5 of the subprojects. Not all of them. Is there a way to run sonarScan sequentially opposed to concurrently?

Here's my stacktrace:

Yes, makes sense. We'll give that a shot. Thanks for the speed response!

Hi, I've never run into this issue before, but it would useful if you could you share a stack trace. I'm curious to see where this exception originates from.

Hi, yes - what you probably want to do is to define an aggregate project across all of your subprojects and trigger the sonarScan job on that project with the aggregate in sonarScan := false setting so that running the scan across all of your subprojects gets delegated to the sonar scanner (it will run them sequentially which will prevent the lock exception from being thrown). Does that make sense?
