I might have misunderstood how this plugin is supposed to be set up but;

I have a job that compiles the source to binaries and archives these, and a job that performs the tests, where the latter requires the artifacts from the former.

Now, since this plugin is only exposed as a build step, and there is not (to my knowledge) possible to archive the artifacts unless as a post-build step - it seems impossible for the test job to be able to retrieve the artifacts needed to execute the tests?

The only way I can imagine is for the test job to be configured so that it executes in the same workspace as the compile job, but then it becomes impossible for the test job to be parallellized across multiple slaves?
