How to use scala 2.10 trunk with sbt 0.11.0? (Unresolved dependencies)

Question

What is the correct way to use sbt with a 2.10 torso? I tried the obvious:

james@James-Moores-iMac :~/workspace/Deleteme3$ cat build.sbt scalaVersion := "2.10.0-SNAPSHOT" 

But it gives:

Answer 1

You cannot use a trunk with SBT 0.11.0, and you can never do this. Newer versions of SBT (snapshots 0.12) can handle it.

Answer 2

Use this version of the actual sbt script: https://raw.github.com/paulp/sbt-extras/master/sbt

Run with

 sbt -sbt-snapshot 

Add this to the build.sbt file:

 scalaVersion := "2.10.0-SNAPSHOT" resolvers += Resolver.sonatypeRepo("snapshots") 

(added as a new answer to combine a couple of answers in one place, but Daniel still answered correctly).
