   There's no problem, if I execute with java command as below.
   ```bash
   java -classpath my-test-0.0.1-jar-with-dependencies.jar:shardingsphere-sql-parser-mysql-4 net.test.Main
   ```
   
   But I changed execute `-jar` as below, I have same problem.
   ```bash
   java -classpath my-test-0.0.1-jar-with-dependencies.jar:shardingsphere-sql-parser-mysql-4.1.0.jar -jar my-test-0.0.1-jar-with-dependencies.jar
   ```
   
   Could it be caused by the class not loading? If so, is there a way to force loading?
