Re: Flink Kafka cannot find org/I0Itec/zkclient/serialize/ZkSerializer

Hi Hawin,

I'm using sbt as shown in the original post. I tried using maven and
pom.xml, but got different NoClassDefFoundError: com/yammer/metrics/Metrics.
I've downloaded metrics-core-2.2.0.jar under lib/ but it doesn't help. It
seems the errors from sbt and Maven belong to same nature. Here is my
pom.xml (standard parts are omitted to make it more readable):
