[rocketmq-connect-jdbc runtime error : NoClassDefFoundError]
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 :)
