Hi,

In the worker\_config , I am specifying the plugin.path as `"/u/goyaltu/Documents/RAFT/raft-core/java/lean-jar"` , so there are 4 jars inside it, two are the lean jars of two connectors - JDBC and PyConnect, and other two are dependencies where one of the jar is dependency of both of the connectors.

In the logs I am able to see all 4 jars from plugin are loaded and registered.  
When I am submitting the connector, it is giving `java.lang.NoClassDefFoundError` which is there in the dependency jar already.

```auto
    "workers": {
      "count": 1,
      "worker_config": {
        "plugin.path": [
	    "/u/goyaltu/Documents/RAFT/raft-core/java/lean-jar"
        ]
      }
    }

```

Can someone help with the problem?

After deploying the connector plugin, did you restart the connect service? This step is mandatory for the connect service to pickup and add the latest connector-specific JARs to the classpath and make them available to the Connect service.
