Free Build Server Service for opensource projects? [closed]

Question

Does anyone know of a free build server service to coincide with scm/forum/issue tracking services such as sourceforge/googlecode?

Obviously hudson/jenkins service would be my first preference related to primarily java/maven2, but anything would be nice!

Thanks!

Cloudbees has an offering for FOSS projects.

Another one (especially for public Github repos): http://travis-ci.org/
