        <Dependency>            <groupId>Mysql</groupId>            <Artifactid>Mysql-connector-java</Artifactid>            <version>6.0.5</version>        </Dependency>

But we use the Springboot framework to write programs that report errors, and there are hints in Pom.xml:

Solution: I removed the MySQL version number to run properly.
