Looks like michael-schnell came up with his own work around by having the resolver resolve a resource and backing in the URL for the Pom. He references a bug that was open in 12/2014 (https://issues.jboss.org/browse/SHRINKRES-214). You can see his workaround in his "utils4maven" project here: utils4maven/MavenPomReader.java at master · fuinorg/utils4maven · GitHub
I'm still thinking that there must be an easier way to do this. Please consider sharing if you have already been down this road.
