For some reason sbt bails on .11.3 when working with the mongodb-record auth project, and it seems to me that's the only version i can download from the git site.
The idiomatic way is to specify sbt version in build.properties as
sbt.version=0.11.2
But since group id in 0.11.3 was changed from org.scala-tools.sbt to org.scala-sbt, sbt can't resolve older versions. But you still can manually download older version of launcher from typesafe repo.
