Simple modification to assembly descriptor to show 671

Karl, I think this is what you are after.
It shows that while the assembly is built, we always get the DEBUG message (and stacktrace)

[DEBUG] Cannot find ArtifactResolver with hint: project-cache-aware
org.codehaus.plexus.component.repository.exception.ComponentLookupException: java.util.NoSuchElementException
      role: org.apache.maven.artifact.resolver.ArtifactResolver
  roleHint: project-cache-aware
