[forge-dev] Project injection issue in a plugin and classloader

Hello Jeremie,

this looks like a "modularity" issue. The JBoss Modules class loading 
seems not to be exporting all the dependencies you require.
I frequently ran into such problems when using classes that where not 
registered with Forge runtime.
During standalone unit tests the modularity restrictions are not yet 
active, so you will not recognize the issue early.
I couldnt go into details of your code but I would suspect something like:

import org.apache.maven.model.Model;

in EclipsePluginFacetImpl.java

During plugin installation the dependencies of your plugin are rewritten 
to the allowed modules, you can verify this by having a look into the 
module.xml of your plugin after installation. If the classes cannot be 
resolved the facet will be silently ignored :-/
Try to stick to the registered and exported classes of Forge runtime.
