Lombok is not working with GWT compile

Question

I have been trying to use Lombok as the latest solution (in some desperation) to my getters/setters problem (I've tried GWT generators, and annotation processors, but Lombok looks like it might be the answer) but I've run into a problem. If I put the annotations in my class:

@Getter @Setter
public class MyModel extends MyAbstractModel {
    private Integer uid;
    //...
}

Then, as expected, Eclipse can see the new methods. I have placed lombok.jar in /lib and put it in the build path, yet when I try and use GWT compile I get errors to the effect that none of the getters/setters exist. If I put them in manually, compile works fine.

I can't work out what is going wrong here, I've even put the -javaagent reference into the VM arguments but no cigar. It just looks like the lombok annotation processors aren't working when GWT compiles (and I've also tried deleting the unitCache but that doesn't work either).

I really don't want to have to write these getters and setters by hand, I have a good 50 or so models, and some of them have 20-30 properties.
