Oh, that's interesting. It looks like the Gradle Wrapper's jar file was intentionally removed from the kafka source tree (https://issues.apache.org/jira/browse/KAFKA-2098), which would cause this error. The README file in the repo says to run "gradle" first, which will install the wrapper binary, which you can then use... but this doesn't work when using gradle 3.0 due to the incompatibility introduced.
The best approach is probably to install an older version of gradle with homebrew. This ought to work: brew unlink gradle brew tap homebrew/versions brew install gradle28 Then you should be able to follow the README instructions, which start with running gradle, then using the gradle wrapper for any builds you want to run.
