Question

I have already installed sbt 0.11.x via brew install sbt. The problem is, I also need to use 0.7.x, but I can’t find a way to install it.

I tried brew versions sbt, but I get just a bunch of warnings

$ brew versions sbt
0.11.0   git checkout e2cdafd /usr/local/Library/Formula/sbt.rb
0.10.1   git checkout ed6327a /usr/local/Library/Formula/sbt.rb

I’m currently running homebrew 0.8 on OS X Lion.

Answer 1

I don’t know why homebrew can’t find the right version, but you could run git show $SHA where $SHA is each of the abbreviated sha1’s that brew couldn’t figure out. Find the one where the commit message tells you it’s updating sbt to 0.7.x, and then use that one.
