Thanks, Jay, Here is what I did this morning, I git clone the latest version of kafka from git, (I am currently using kafka 8.0) now it is 8.1.1, and it use gradle to build project. I am having trouble to build it. I installed gradle, and run ./gradlew jar in kafka root directory, it comes out: Error: Could not find or load main class org.gradle.wrapper.GradleWrapperMain
Any idea about this. Thanks Alec On Wed, Oct 1, 2014 at 9:21 PM, Jay Kreps <jay.kr...@gmail.com> wrote: > Hi Sa, > > That script was developed with the new producer that is included on > trunk.
