@yuxiqian Can you help to review this?

Seems CI is failing since https://github.com/apache/flink-cdc/commit/17ff659ff72e6d144e06256ed12162e604dc4804 doesn't generate test jar by default, which is required by Paimon E2e tests. Some changes like

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-jar-plugin</artifactId>
                <executions>
                    <execution>
                        <id>test-jar</id>
                        <goals>
                            <goal>test-jar</goal>
                        </goals>
                    </execution>
                </executions>
            </plugin>
        </plugins>
    </build>

might be necessary.

Close this and trace in https://github.com/apache/flink-cdc/pull/3818 as this pr rely on https://github.com/apache/flink-cdc/pull/3818 to fix some bugs and https://github.com/apache/flink-cdc/pull/3818 also need to verify by e2e.
