Looks like, since this is an unconventional package, the
maven-compiler-plugin is not bound to the maven lifecycle.
The java configurator is trying to infer the java version from the
maven-compiler-plugin configuration, but fails. You can try adding
<plugin>
<artifactId>maven-compiler-plugin</artifactId>
<version>2.3.2</version>
</plugin>
in your <plugins> node. I'm not sure it'll work. In any case, you should
open an issue at https://bugs.eclipse.org/bugs/enter_bug.cgi?product=m2e
