Caused by: org.apache.kafka.common.config.ConfigException: Invalid value
org.apache.kafka.common.serialization.ByteArraySerializer for configuration
key.serializer: Class org.apache.kafka.common.serialization.ByteArraySerializer
could not be found.
But adding kafka-clients to the maven plugin changes that:

Which then results in:

info ?
