Dragos Manolescu commented on KAFKA-797:
----------------------------------------
I second David's and Phil's observations, the scala-compiler and scala-library
JARs are not downloaded by sbt: I wiped the ivy cache and ran into the same
problem. I also agree that referencing ~/.ivy2/cache from the classpath is
asking for trouble ;)
Poking around the build file I noticed that the sbt-assembly plugin is already
there, though nothing seems to be using it. Perhaps leveraging it to package
all dependencies into a single jar would be more robust than extending the
classpath with individual JARs in kafka-run-class.sh?
