The error occurs only in direcotry a/b (the build in dir a and in dir a/b/b.a works fine):
$> cd ~/a/b
$> mvn compile

Version: I
It seems that there is a problem with more than one parent with packaging=pom.
The <relativePath>--Element didn't help. The only workearound (suggested in the maven user mailing list) is, to deploy the parent
poms to the maven repo.
