The only dependency which currently "fits" my definitions is jboss-logging. It is only used internally and its APIs are not "re-exported". My PR also includes a simple integration test for the "embedded" case. I will obviously integrate it with tests with the others once we agree on the structure. >> Just for my own understanding, what is the rationale behind this?

Shade actually pulls in the dependency tree automatically so I don't have to think about these things (and the Infinispan Query dependency hierarchy is hairier than a sea otter). > More importantly: is the user meant to use these as Either/OR or as > additive packages?

infinispan-embedded-query would still depend on infinispan-embedded, so the user would require both jars. For the maven user, just depending on infinispan-embedded-query will do the trick, since infinispan-embedded would be a transitive. > Much simpler this way, so why not making this the default packaging? > The "uber" jars are what we should advertise in our quickstarts, docs, etc. Obviously the single underlying jars would still be deployed to maven.
