Description

Config of plugin is fairly simple, but fails with the error below when I call "mvn package test", it works when I call only "mvn package", it seems the plugin tries to open a directory as zip-file.

It happens in a multi-module setup when building from the parent-directory. It seems the dependency between the module where the shade plugin runs onto another module causes the target/classes of that module to be added as artifact-file, which causes the shade plugin to fail.

Let me know if you need a self-contained reproducer project, I can provide one, but it will take some time to build it...

FYI, there was a similar problem in the war plugin at MWAR-192.
