Apache Ignite Kafka Streamer 不工作，获取 java.lang.NoClassDefFoundError：无法初始化类

Question

遵循此处提到的说明： https://ignite.apache.org/docs/latest/extensions-and-integrations/streaming/kafka-streamer

但仍然出现以下错误：

WorkerSinkTask{id=my-ignite-sink-connector-1} Task threw an uncaught and unrecoverable exception. Task is being killed and will not recover until manually restarted.
