Description

We are running all of our CI builds with the release profile so that javadocs and sources are generated. However, one module in a multi-module build contains only test sources. After updating from 2.0.4 to 2.1 the build will fail. The same error occurs when source:jar is run manually. Below is the stack trace from jar:source. It might be intentional that the build will fail in case source:jar is run from command line, but when using release profile the failure is quite problematic.
