If it works, I can fix this as a workaround in forge for now, but it's not the right solution in the long run, and we'll have to get weld fixed up. I'm working on creating a custom WeldBootstrap application that adds each plugin as a deployablearchive, but that's going to take some time unless I can get help from the weld guys.
