Could not initialize class io.lettuce.core.ClientOptions

[oNddleo]

I have a problem when i created kafka connect redis:
{"name":"sink","connector":{"state":"RUNNING","worker_id":"connect:8083"},"tasks":[{"id":0,"state":"FAILED","worker_id":"connect:8083","trace":"java.lang.NoClassDefFoundError: Could not initialize class io.lettuce.core.ClientOptions\n\tat com.github.jcustenborder.kafka.connect.redis.RedisSessionFactoryImpl$RedisSessionImpl.create(RedisSessionFactoryImpl.java:157)\n\tat com.github.jcustenborder.kafka.connect.redis.RedisSessionFactoryImpl.create(RedisSessionFactoryImpl.java:52)\n\tat com.github.jcustenborder.kafka.connect.redis.RedisSinkTask.start(RedisSinkTask.java:73)\n\tat org.apache.kafka.connect.runtime.WorkerSinkTask.initializeAndStart(WorkerSinkTask.java:300)\n\tat org.apache.kafka.connect.runtime.WorkerSinkTask.execute(WorkerSinkTask.java:189)\n\tat org.apache.kafka.connect.runtime.WorkerTask.doRun(WorkerTask.java:177)\n\tat org.apache.kafka.connect.runtime.WorkerTask.run(WorkerTask.java:227)\n\tat java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511)\n\tat java.util.concurrent.FutureTask.run(FutureTask.java:266)\n\tat java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149)\n\tat java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624)\n\tat java.lang.Thread.run(Thread.java:748)\n"}],"type":"sink"}
I don't know that is error by library or my config of kafka connect redis.

@oNddleo How did you do the install? You need to make sure that you have all of the dependencies as well. Easiest way to install is via the Confluent Hub

Yeah, I sure that your repository i download and it called by docker

Can you post more info about your docker file? Here are a couple examples of how I do do the install. The big key is to ensure that the plugin path is correct.

https://github.com/jcustenborder/cp-kafka-connect/blob/6.1.0/Dockerfile#L22
https://github.com/jcustenborder/cp-server-connect-operator/blob/6.1.0/Dockerfile#L22

Thanks, I will retry.
I checked it inside /usr/share/confluent-hub-components but when i create sinkconnector with curl so above exception

That's my Dockerfile, i use kafka redis and mongo connector all of us, kafka mongo connector successed but redis not, so I not found reason.

Interesting. What happens if you use a later version of cp-kafka-connect?

My bad not trying another version. Thanks your reply. I will try this.

Thanks you very much. I fix that with later version.
