Currently the plugin shows some Java warnings in the source code of the plugin. It would be nice to have those removed or at least reduced.

Background: I was patching the source code of the plugin to add an feature. Therefore I also reduced (one is still missing) the Java warnings in the source code.

Those are of the type: Unused imports, unused variable, deprecated Hudson.getInstance(), missing UUID, missing option in switch.

As I wanted to share the work I will add an pull-request for this issue.
