First issue is to get this plugin building.

I am new to the Jenkins org so please comment if you know something, I might not.

The last build I see is:
https://ci.jenkins.io/blue/organizations/jenkins/Plugins%2Fconfigurationslicing-plugin/detail/master/2/pipeline
oleg_nenashev  Is this a failure in the plugin build or the build system itself? I can't see any log indicating what failed on the plugin side of things.
