Ewen Cheslack-Postava commented on KAFKA-2030:
----------------------------------------------
It looks like the homebrew bottle was compiled with Java 8 and you have a
different version. The homebrew package isn't maintained here. The packaging
script that generates the package is at
https://github.com/Homebrew/homebrew/blob/master/Library/Formula/kafka.rb and
you'll want to file a bug against that repository. Not sure if homebrew has a
build_depends in addition to their depends settings, which is probably how
you'd have to enforce something like building with JDK6 to get full
compatibility. Not sure which version you're trying to run with, but it looks
like they are only supporting 1.7+, whereas Kafka can still be built with JDK6
so even if they fix the bottle to match the formula it's possible it still
wouldn't work for you.
You might also want to look at:
https://github.com/Homebrew/homebrew/blob/master/share/doc/homebrew/Bottles.md
You could probably fix this by just turning off bottles. It'll have to build
everything from scratch, but should definitely be compatible with whatever Java
version you're using.
