Check if your target/addons folder contains the deployed addons structure. It should have been created by the furnace-maven-plugin

If I'm right, Roaster is nice to add bits and pieces of Java here and there, but it's better to use Templates when there is a lot of code, and mix templating and Roaster for better code customization.
