My sbt version is sbt 0.11.3. It's my first project with sbt.
Head over to scala-sbt.org to find the latest stable version (as of April 2014, it's 0.13.2).
If for some reason you have to use sbt 0.11.3, here are the plugin versions you could try:
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.8.7")
addSbtPlugin("com.typesafe.sbt" % "sbt-scalariform" % "1.0.0")
I wasn't able to find the other plugins for sbt 0.11.3. Not sure if they existed back then.
