strategoxt repository not available

[jbracker]

I am trying to use SugarHaskell. As the current build does not seem to work, I was trying to build from source and maybe get the problem fixed. When attempting to build with maven I get this error:

I called mvn3 install. My Java is rusty and I have not used maven before, therefore I don't know what exactly is going wrong. But judging from the error message and the sources I guess this pops up because http://download.spoofax.org/update/nightly/ is not available anymore. I tried to find an alternative location but wasn't successful.

I would really like to try and experiment with SugarHaskell and would apprciate help a lot.
