Are you using Spring Boot? I know that the recent Spring Boot 2.2.0 release specifically updates their Kafka dependency to 2.3.0. Previous version used Kafka 2.1.x though I've used 2.2.x with it.
Maybe running mvn dependency:tree would help see if there are multiple Kafka versions that could conflict. On Thu, 24 Oct 2019 at 20:14, Matthias J.
