derek commented on KAFKA-139:
-----------------------------
1. You should be able to simply update the sbt-launch.jar under lib/ to get SBT
working on a fresh kafka checkout without having to use PaulP's script.
2. I've fixed it so the build defaults to 2.8.0. The -28 option isn't what you
want. I believe that runs SBT under 2.8.2, not the compilation, etc
3. The idea plugin changed a little. The new syntax is "./sbt gen-idea"
I'm attaching a revised patch with some minor tweaks to fix a bug in the cross
build and to make 2.8.0 the default. Please let me know if you have further
concerns/questions

> Since scala does not maintain binary compatibly between versions,
> organizations tend to have to move all of there code at the same time. It
> would thus be very helpful if we could cross build multiple scala versions.

> Unclear if this would require KAFKA-134 or just work.
