Jun Rao commented on KAFKA-139:
-------------------------------
Joe, after your check in. I saw a couple of changes: (1) ./sbt package received
a bunch of warnings during compilation; (2) bin/kafka-server-start.sh
config/server.properties stopped working with the following error
bin/kafka-server-start.sh config/server.properties
Exception in thread "main" java.lang.NoClassDefFoundError: kafka/Kafka
Caused by: java.lang.ClassNotFoundException: kafka.Kafka

Could not find the main class: kafka.Kafka. Program will exit.
It seems that kafka/kafka.class is no longer in the Kafka jar.
> cross-compile multiple Scala versions and upgrade to SBT 0.12.1

> 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.
