The exception seems to be caused by the fact that the Jenkins Job name is different from the actual POM's artifactId and it tries to use the former to get the version of the latter.
Attached patch fixes the issue for me but I'm unsure if this is the correct way to go about it. It does seem to fix the issue for us though for both single and multi-module Maven projects.
If this is the/a correct fix I can send a pull request if you prefer.
