Thanks a lot John, this is exactly what I needed :) Based on the plugin configuration you suggested, I added promoteTransitiveDependencies property and set it to true so that transitive dependencies become direct dependencies in the shaded jar.
But I have one problem yet : I need to add some files to the shaded jar. I saw you can exclude files from the shaded jar with filters property, but I can't see a way to add a new file to the shaded jar. I thought about creating a new artifact in M2 repository with these files to add and add this artifact to the artifactSet includes property. It should work but I wonder if there's an easier way to do it. Do you have any idea about this ?
