Since the change to use the HK2 2.0 API, the hk2-jar maven plugin is no longer being used to generate JAR files. This means that there are no longer Class-Path entries in the manifests for JAR files. However, for the asadmin command, Class-Path entries are still required.
Specifically, the gms-adapter.jar file needs a class-path entry that points to shoal-gms-impl.jar. For now, this has been manually put into the pom.xml file gms-adapter.jar. This issue is for figuring out a way to do this automatically so that the dependencies that are already listed in the pom.xml are picked up.
