Here are slides and source code for my talk at GR8Conf US 2012. The source code and slides are available as a zip.
You can also access the slides and source code from the GR8 Conf US 2012 github repository.
To play with the sample projects and DSL descriptors, you should start with a snapshot version of Groovy-Eclipse 2.7.1 and import the two projects from the zip file into your workspace.
The best place to get your questions answered is on the Groovy-Eclipse mailing list.
