--------------------------------------------------------------
Here is a very simple Gradle project that compiles and tests the "core" part of
the Kafka source tree.
Notable things missing:
* Multiple versions of Scala (http://issues.gradle.org/browse/GRADLE-2478)
* Other sub-modules (perf, contrib, etc)
* Release packaging
* Gradle wrapper (to avoid developers needing it installed system-wide)
* Other stuff I'm forgetting at the moment
As I understand it, all of these things are possible with existing Gradle
plugins except for multiple Scala versions - couldn't find an answer there.
Compared with the Ant build, it is much less verbose, but less flexible. Doing
things like cross-targeting Scala is pretty cut-and-dry with Ant. Setting up
this simple project up didn't take me very long (~1.5 hours) but I did run into
some bad documentation from Gradle's website and some unhelpful errors. Here
are two of the more fun errors I encountered:
https://gist.github.com/mumrah/6de7be3d6640059904b5
The error messaging gives me pause, b/c (in my experience) it's almost
immediately obvious what went wrong with your build in Ant. Also notice that
Gradle is calling the ant scalac target.
Looking forward hear to what others think!

> Key: KAFKA-1171
> URL: https://issues.apache.org/jira/browse/KAFKA-1171
> Project: Kafka
> Issue Type: Improvement
> Components: packaging
> Affects Versions: 0.8.1, 0.9.0
> Reporter: David Arthur
> Assignee: David Arthur
> Attachments: 0001-Adding-basic-Gradle-build.patch
>
>
> We have previously discussed moving away from SBT to an
> easier-to-comprehend-and-debug build system such as Ant or Gradle. I put up a
> patch for an Ant+Ivy build a while ago[1], and it sounded like people wanted
> to check out Gradle as well.
