I wanted to use Configgy with Scala 2.8, so I created a branch in my GitHub repository:
The main code now compiles, but the tests and the build system have to be updated still.
I’m not particularly familiar with Ivy, so if someone else wants to do that, I won’t complain. ;)
The tests use specs and Eric has already released a binary for 2.8.0.
Update: I filed an issue upstream to track 2.8 support.
Update 2: The branch has been updated to Scala 2.8.0.Beta1-RC3 along with the build system and the tests pass. Thanks to paulp for tracking an issue that was taking place because the stack order changed in Scala 2.8.0.
