Mark, That's a slightly strange error. 51.0 is the class version associated with Java 7, so it seems to indicate that the "smx3.api.EntityProvider" class was compiled with javac 7 but you are not actually running it on Java 7.
Do you have other Java versions installed on the same machine, and is it possible that Maven has picked up one of the other ones? Also, did you compile the Maven SCR plugin locally? It would be surprising to me if the binaries for the plugin are being shipped with class version 51.0, implying they can only run on Java 7.
