Jenkins（003）手贱卸载了Role

手贱卸载了Role-based Authorization Strategy导致的问题

学习Jenkins过程中，发现Jenkins给新建用户分配角色权限时，点击add不生效，怀疑是插件版本和jenkins版本对应不上导致的，于是就想卸载掉插件，找个低版本插件安装，结果卸载完重启Jenkins就歇菜了。

从文件内容可以看出，这里面有权限插件模块的部分定义，你会发现报错的类就在xml定义了。 因为插件被卸载，这部分定义内容还在，所以启动也就出大问题。 解决方法： 备份 Jenkins 家目录下的 config.xml 修改原 config.xml，删除这部分内容

<authorizationStrategy> ... </authorizationStrategy>

重启服务，访问成功

至于Jenkins给新建用户分配角色权限时，点击add不生效，是浏览器问题导致，换成Google浏览器就能正常add，真心服气。
