ETL--连接MySQL报错-- Driver class 'org.gjt.mm.mysql.Driver' could not be found, make sure the 'MySQL' driver (jar file) is installed. org.gjt.mm.mysql.Driver

错误展示：

1.获取jar包

https://downloads.mysql.com/archives/c-j/

2.添加进lib

D:\etl\data-integration\lib

3.启动或重启

ps：
MySQL5和MySQL8的connector的jar包中jdbc的路径不同，分别如下：
mysql-connector-java-5.1.37-bin.jar\com\mysql\jdbc
mysql-connector-java-8.0.11.jar\com\mysql\cj\jdbc
Kettl 7默认在jar包中的这个路径下寻找\com\mysql\jdbc
