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.

Hmm, I probably messed up and used a build with additional debug statements, my apologies for that.

This is the exception with a vanilla 0.1.2 plugin form the update center (double checked it this time):

It doesn't seem to happen with the latest version from Git anymore, so it seems cb9649c has fixed it.

I'm not sure if it's fixed

The exception is thrown due to a null Job's configuration and I haven't found a reproducible conditions in which it's thrown

Just to confirm the new version, 0.2.0, fixes the problems I was seeing. Thanks.
