I have a code generator on UML2 on my project. It's pom file is the following :

I'm using the p2 resolution to get all the dependencies for the Acceleo compilation cycle. I had to add a few requirements in my Manifest.MF to force the resolution (If I could add those in the pom.xml and not in the manifest it would be nice ^^) :

 org.eclipse.uml2.uml,
 org.eclipse.acceleo.parser,
 org.eclipse.acceleo.common,
 org.eclipse.acceleo.profiler

The build is failing with a : 

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.1.1:java (default)l
[ERROR] 2:The metamodel couldn't be resolved
[ERROR] 5:Invalid Type: Model
[ERROR] 8:Unrecognized variable: (name)
[ERROR] 8:Unrecognized variable: (name)
[ERROR] -> [Help 1]


Looks like the parser is not able to register the required EMF Package (here UMLPackage).

I'm quite sure I don't even have a workaround here :/
