URL: https://github.com/apache/seatunnel/issues/9495#issuecomment-3795708600
This issue is caused by multiple instances of the `debezium-core` library on
the classpath:
1. One transitively brought in by `debezium-connector-mysql`.
2. Another provided by `connector-cdc-base` (which relies on
`debezium-core`).
This results in the `TableId` class being loaded by different class loaders
or from different JAR versions, leading to a `ClassCastException`.
## Solution
Modified `seatunnel-connectors-v2/connector-cdc/connector-cdc-mysql/pom.xml`
to exclude `debezium-core` and `debezium-api` from the
`debezium-connector-mysql` dependency. This ensures the project consistently
uses the Debezium core classes provided by `connector-cdc-base`.
### Changes Applied to `pom.xml`
```xml
<dependency>
<groupId>io.debezium</groupId>
<artifactId>debezium-connector-mysql</artifactId>
<exclusions>
<exclusion>
<groupId>mysql</groupId>
<artifactId>mysql-connector-java</artifactId>
</exclusion>
<!-- Added exclusions to prevent ClassCastException -->
<exclusion>
<groupId>io.debezium</groupId>
<artifactId>debezium-core</artifactId>
</exclusion>
<exclusion>
<groupId>io.debezium</groupId>
<artifactId>debezium-api</artifactId>
</exclusion>
</exclusions>
</dependency>
```
## Verification
After applying this fix, reload the Maven project to update dependencies.
The `SeaTunnelEngineLocalExample` should now run without the
`ClassCastException`.
