How to change Scala version in SBT/Android Plugin/Project?

Question

I'm using SBT v0.13 with jberkel/android-plugin, which I am trying to modify.

In order to do that, I need to work with Scala 2.10.0-20120710-144914-026a70d555 in my test project.

So far, I've used Scala 2.9.1, and I need to switch to 2.10.0-20120710-144914-026a70d555 now, but I'm not so proficient with this stuff.

I've ran into this question, but that doesn't work for me.

I get the following output when I try to compile and push my test application to device:

Answer 1

I think you need

set scalaVersion := "2.10.0-SNAPSHOT"

It will automatically pick the latest published scala version.
