project asset jar not copied to stage/distribution in a multi-module project

Plugin version 0.6

After running `gradle stage/dist`, I can see that 2 jar files created under `build/libs` folder, one for jar/scala classes, and one for assets, the `public` folder. These files are generally web assets, like js/html files. I can see that module jar/asssets files are copied but for main project, only `project.jar` file present in the `build/stage/main/lib`, folder, not `project-assets.jar`. This causes app start but without ant static Web files. When manually copying assets.jar, app works as expected.
