As shwown in this tutorial, during development you should use the normal mysql driver and only appengine use the Google mysql driver

  if (SystemProperty.environment.value() ==
      SystemProperty.Environment.Value.Production) {
    // Load the class that provides the new "jdbc:google:mysql://" prefix.
    Class.forName("com.mysql.jdbc.GoogleDriver");
    url = "jdbc:google:mysql://your-project-id:your-instance-name/guestbook?user=root";
  } else {
    // Local MySQL instance to use during development.
    Class.forName("com.mysql.jdbc.Driver");
    url = "jdbc:mysql://127.0.0.1:3306/guestbook?user=root";
  }

Also double check that you have enabled MySQL Connector/J for your application (it's not done by default)
