Maven doesn't know what type of artifact your dependency is referring

is always a good idea.
I haven't tried this (don't know if it's supported either) but maybe
you can specify <type>jar</type> in the m2 dependency, so it won't need
the POM, but my guess is that this doesn't work and you still need
the pom.
