Just tried that - it works fine, so I’ve learnt something new. Good solution!

I’d previously thought that “optional” meant on the compile classpath but not the runtime classpath, but I guess it means on the artefact’s own runtime classpath but not a transitive dependency. So it does exactly what you want if you want your artefact to be both a process and a library. Perfect.
