Jun Rao commented on KAFKA-139:
-------------------------------
I did a new checkout of 0.8 branch, applied patch v3 and copied the
sbt-launch.jar to lib. I still got the following error:
[jrao@jrao-ld kafka_0.8_temp]$ ./sbt gen-idea
[warn] Using project/plugins/ is deprecated for plugin configuration
(/home/jrao/Intellij_workspace/kafka_0.8_temp/project/plugins).
[warn] Put .sbt plugin definitions directly in project/,

> Issue Type: Improvement
> Components: packaging
> Affects Versions: 0.8
> Reporter: Chris Burroughs
> Labels: build
> Fix For: 0.8

> Attachments: kafka-sbt0-11-3-0.8-v2.patch,

>
> 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.
