Minor Description
URL should be changed from https://maven.objectstyle.org/nexus/content/groups/cayenne-deps to https://maven.objectstyle.org/repos/cayenne-deps/ as Objectstyle shuts down its Nexus and changes this repo to a static files.
5.0 doesn't use this repo as it doesn't use any dependencies that are not in Central. For other versions we are not intended to add any non-central dependencies, so there should be no problems. And potentially this could speed up builds a bit as Nexus could be really slow some times.
