Hi Phil, I have already seen the issue previously, and I believe it is now fixed on master. As you can see here, https://github.com/guix-mirror/guix/blob/master/gnu/packages/java.scm#L7899 we now propagate the correct parent pom.
In particular, java-jmh is a much more complex package, and it builds fine with the maven-build-system. So I suggest you to pull to the latest master commit and enjoy :) Don't hesitate to get back if you still have issues on master, I'll be happy to help!
