Specifically, the error arises when the maevn-jar-plugin has a classifier in its configuration.

> It's due to the shade plugin whose tries to reference first module classes from target/classes
repository instead of the jar file previously build.
> Therefore, it seems that the shade plugin doesn't work with a maven multimodules project.
> I manage to build my maven aggregator project by applying the attached patch (patch-maven-shade-plugin.txt)
on the class
