I'm trying to build a very small (only 4 classes up to now) maven3 project in jenkins.
After the build is finished an exception is thrown somewhere in jenkins code, causing the build to be 'red'.

I've only installed the GIT plugin, other than that its basically an of the shelf installation.
You find the project here:
https://github.com/smurn/gpsutils/

Here are the final lines of the log (I've attached the complete log):
