[GitHub] [camel-kafka-connector-examples] milkchocolate opened a new issue #327: Failed to run the github-source-events example
milkchocolate opened a new issue #327:
URL: https://github.com/apache/camel-kafka-connector-examples/issues/327
Hi team, I run into an issue when I run the github-source-events example, can you help me on this?
### How I run the example
I think I strictly follow `github/github-source-events/README.adoc`, the only difference is I use Docker for local Kafka environment, the `connect-standalone.sh` script is executed inside the Kafka container.
### The issue I run into
At the last step, when I run the commad, it throws an error.
**Command:** `{path}/connect-standalone.sh {path}/connect-standalone.properties {path}/CamelGithubSourceConnector.properties`
**Error:** Failed to find any class that implements Connector and which name matches org.apache.camel.kafkaconnector.github.CamelGithubSourceConnector
### Files from untar.gz github-extended-0.11.0-package.tar.gz
### connect-standalone.properties
### CamelGithubSourceConnector.properties
### Detailed Error

Hi Andrea,
I got the example running on my machine, thanks for your guiding👍
When I switched to local Kafka, I ran into another issue, it said
`java.lang.NoClassDefFoundError: org/apache/camel/kafkaconnector/CamelSourceConnectorConfig`.
I was stuck by the issue for hours, then I made the change below to get everything work, is that correct?
1. When I extract the github-extended-0.11.0-package.tar.gz file, I get a folder called "github-extended" with jars in it.
2. So I set the plugin.path to "{path}/{parent-folder}/github-extended".
3. The change I made is set the plugin.path to {path}/{parent-folder}.

The plugin path point to a directoy where you'll have one or more connector, so pointing to the topc parent-folder is right.

First try the example locally. There are no instructions for it on docker.

Also the plugin path must exists where you're running the kafka connect standalone, so you need to mount the plugin path folder from your host or copy the plugin path content in the container before starting the connect standalone.
