        </plugins>
    </build>
</project>

This is the main function

package org.kuohai;

public class TestNGMain {
    public static void main(String[] args) {
        org.testng.TestNG.main(args);
    }
}

Then you can use :

mvn clean package -DskipTests

Package and run

java -jar packageName.jar -testjar packageName.jar 

If you have other questions, you can run java -jar packageName.jar

You can see the message.
