what happened to the annotations?

it doesn't compile with the annotations :( but it's something to start with and the annotations in mirah will be fully supported soon.

And... annotations are back and working!

So mirah knows to put annotations on the initialize method on the java constructor?

Yes, the plugin compiles and it's loaded properly, now we have another problem, hudson needs the descriptor uses a generic to know what kind of extension is, builder or publisher for instance, and mirah doesn't support generics right now. I'll talk with headius to see what we can do.
