Simple-Build-Tool: Error Getting Started

I’m starting in Scala, because Seevibes’ code is in Scala. Scala has a tool named simple-build-tool for managing your projects. sbt is similar to Ruby’s Bundler and Clojure’s Leiningen in that it manages dependencies and helps build a project for you.

Unfortunately, I had problems getting started. After following the Setup instructions, I was consistently getting this error:

1 Getting org.scala-tools.sbt sbt_2.8.1 0.10.1 ...

27 Error during sbt execution: Error retrieving required libraries

29 Error: Could not retrieve sbt 0.10.1

I hit #scala and RSchulz pointed me to ~/.ivy2. After I rm -rf’d ~/.ivy2 and ~/.m2, sbt ran to completion. I was unable to find any mentions of the errors above, so hopefully this may help someone else.
