datax支持的人大金仓是v8版本而不是v7吗？如果是v7的话怎么使用呢

1、我现在用datax自带的kingbaseesreader链接不成功，错误为jdbc驱动问题；
2、我查看了kingbase的版本发现本地的版本是v7，而kingbaseesreader中带的驱动包是v8
3、现在我初步的想法是：
1、将kingbaseesreader下的v8驱动包换成v7的试一下
2、把plugin.json里面仿照rdbmsreader写一行drivers

Start by inspecting the kingbaseesreader plugin, its bundled V8 JDBC driver, and plugin.json, then compare them with the locally reported Kingbase V7 setup. Reproduce the connection failure with the available configuration. Done means establishing whether V7 is supported and identifying the required driver or configuration change.
