We have Jenkins ver. 1.651.3 and I suspect it's the maven-plugin (2.12) that is occasionally causing such errors in a build. A simple rebuild no longer runs into the same problem.

I have found similar error reports but mostly related to the release plugin or Maven 2. Our job is a 'standard' Maven project running mvn3.
