Class 在 debezium db2 kafka connect 中找不到 DB2Driver

Question

我正在尝试使用 Kafka 连接（debezium 不可变 docker 图像）部署 debezium db2 连接器。但是当我使用 kafka REST api 部署 db2 连接器时，它在 kafka 连接日志中给出了以下错误。

我参考了以下教程 https://debezium.io/documentation/reference/tutorial.html#starting-kafka-connect

Answer 1

我已经使用 bin bash 登录到 kafka connect，并将 db2 dependancies jar 从我的本地文件夹复制到 lib 文件夹。这解决了我的问题。
