I think the problem is that this configuration needs to be added to the hello-impl and stream-impl sub-modules, rather than to the top-level pom.xml.

In addition, the mainClass configuration in the README doesn't apply to Lagom (or Play) applications.

We should update the README (or the documentation at https://developer.lightbend.com/docs/lightbend-orchestration/current/) to have more specific details about how to apply this to Lagom, Play, and Akka applications.
