Ooh, right, thanks! In case there will be another newbie reading this: The output from "mvn package" contains the last exception thrown, but it's not the whole log!
Running the individual test gave the full log: mvn test -Dtest=com.google.jenkins.plugins.storage.ClassicUploadStepTest In my case I haven't mocked out getDescriptor(), so it returns nullptr and the server dies with NullPointerException Thanks for getting me on track again!
