imaffe opened a new issue #535: [rocketmq-connect-jdbc runtime error : NoClassDefFoundError] URL: https://github.com/apache/rocketmq-externals/issues/535 The issue tracker is **ONLY** used for bug report and feature request. Any question or RocketMQ proposal please use our [mailing lists](http://rocketmq.apache.org/about/contact/). **BUG REPORT** 1. Please describe the issue you observed: - What did you do (The steps to reproduce)? 1. run rocketmq-connect-runtime 2. try to start rocketmq-connect-jdbc source and sink connectors - What did you expect to see? Run without error - What did you see instead? ``` java.lang.NoClassDefFoundError: org/apache/rocketmq/tools/admin/DefaultMQAdminExt at org.apache.rocketmq.connect.jdbc.connector.JdbcSinkConnector.startMQAdminTools(JdbcSinkConnector.java:55) ``` 2. Please tell us about your environment: ubuntu server 16.04 lts java 8 rocketmq-connect: 0.0.1 snapshot roccketmq-connect-jdbc: rocketmq-connect-jdbc-0.0.1-SNAPSHOT.jar 3. Other information (e.g. detailed explanation, logs, related issues, suggestions how to fix, etc): Because it's a NoClassDefFoundError, so I guess it's because `import org.apache.rocketmq.tools.admin.DefaultMQAdminExt` and `org.apache.rocketmq.tools` is not in class path when runtime starts. I checked the ./lib of runtime, and found there is only ``` ll ~/rocketmq-externals/rocketmq-connect/rocketmq-connect-runtime/target/distribution/lib # output ... -rw-rw-r-- 1 affe affe 333224 Mar 25 06:25 rocketmq-client-4.5.2.jar -rw-rw-r-- 1 affe affe 284472 Mar 25 06:25 rocketmq-common-4.5.2.jar -rw-rw-r-- 1 affe affe 134940 Mar 25 06:25 rocketmq-connect-runtime-0.0.1-SNAPSHOT.jar -rw-rw-r-- 1 affe affe 63747 Mar 25 06:25 rocketmq-logging-4.5.2.jar -rw-rw-r-- 1 affe affe 121105 Mar 25 06:25 rocketmq-remoting-4.5.2.jar ... ``` So maybe add `rocketmq-tools-4.x.x.jar` should solve the problem. But since they are all within the rocketmq artifact, I don't know how to find the `rocketmq-tools-4.x.x.jar`. I guess `rocketmq-tools` was added recently? Hope this helps :)
