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

Question

What's the right way to use sbt with 2.10 trunk? I tried the obvious:

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

But that gives:

james@James-Moores-iMac:~/workspace/Deleteme3$ sbt compile

Trying the suggestion of the new sbt launcher with -sbt-snapshot fails too:

james@James-Moores-iMac:/tmp/sfasdf$ sbt -sbt-snapshot compile

Answer 1

You cannot use trunk with SBT 0.11.0, and you'll never be able to do so. Newer SBT versions (snapshots of 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 your build.sbt file:

scalaVersion := "2.10.0-SNAPSHOT"

resolvers += Resolver.sonatypeRepo("snapshots")
