(was: Hi,
     I have submitted a patch for this. Basically the patch checks whether the java process returns with an exit code of 1 (abnormal), and if it does checks the output of the java process to see whether there are NoClassDefFoundError or "Could not find or load main class" messages and then if it does, displays this message:

"Please build the project using sbt. Documentation is available at http://kafka.apache.org/"

Please let me know if you have any concerns with this approach.)
