【中文标题】有没有办法为这个 debezium 连接器设置一个接收器和源连接器？【英文标题】：Is there a way to setup a sink and source connector for this debezium connector? 【发布时间】：2021-04-19 13:57:31 【问题描述】：

我正在使用这里找到的 debezium-connector：https://repo1.maven.org/maven2/io/debezium/debezium-connector-oracle/1.4.0.Final/debezium-connector-oracle-1.4.0.Final-plugin.tar.gz

我正在按照 docker-compose 的这些说明进行操作：https://github.com/confluentinc/demo-scene/blob/master/oracle-and-kafka/docker-compose.yml

我使用 confluent-hub 为 jdbc-connector 完成了此操作，但我不知道如何为 debezium 执行此操作。添加到 /usr/share/java 并运行是解决不了的

所以我的 docker-compose 是：

【问题讨论】：

你有一个安装路径/etc/kafka-connect/jars，但没有在CONNECT_PLUGIN_PATH中使用它 【参考方案1】：

你需要将/etc/kafka-connect/jars添加到CONNECT_PLUGIN_PATH
