Hi Dave, Here's a POM I use to build the examples. It's pretty simple, including kafka 0.8.0 with scala 2.9.2 libs, and targeting Java 7. I also made a couple of mods to make things easier:
1) I use log4j 1.2.17 to eliminate a log4j 1.2.15 dependency on the sun jdmk. 2) I use the maven dependency plugin to build a lib folder that has all the jars you need for the runtime classpath. Hope it helps, Steve On Tue, May 6, 2014 at 8:11 AM, David Novogrodsky < [email protected]> wrote: > All, > > I am running some examples from the packet book Apache Kafka.
