I have a Scala project consisting of a few ones. I decided to start using sbt 0.13. Here is ~/sbt/repositories:
0.13
~/sbt/repositories
[repositories] local
Try using 0.13.1.
0.13.1
Put the following in project/build.properties:
project/build.properties
sbt.version=0.13.1
You will probably need the 0.13 sbt launcher as well. See sbt Getting-Started - Setup
