groovy-swt forked?

[François Rey]

Is there any reason why groovy-swt was forked into this project?
I tried to upgrade the libs to groovy 1.8 but then ran into some issues related to groovy-swt. I was expecting some groovy-swt jar but realized it was in source form. I'm not sure how to solve this issue. I did try compile the plugin with groovy 1.8 and there was no error building the plugins/features/sites with 1.8 jars (also upgraded commons and ivy jars).
Any suggestions would be great.
Here's the error I get:

Nevermind I found the error, my mistake forgetting to update MANIFEST.MF.
Still, the question of why forking groovy-swt remains…
