插件更新，重启jenkins报以上错误，原因: Caffeine API插件或者Role-Based Authorization插件和jenkins版本不兼容导致的

解决办法：

一、禁用角色权限，进入jenkins后，插件更换成上个版本
1、停止jenkins，修改config文件，临时禁用角色权限

<authorizationStrategy class="com.michelin.cio.hudson.plugins.rolestrategy.RoleBasedAuthorizationStrategy">
...（原有配置）...
</authorizationStrategy>

修改为

<authorizationStrategy class="hudson.security.AuthorizationStrategy$Unsecured"/>

2、启动jenkins，进入jenkins后，插件更换成上个版本

systemctl start jenkins

3、重启测试是否正常

二、使用以前的备份文件，还原插件

1、备份插件还原

2、修改权限

chown -R jenkins:jenkins /var/lib/jenkins/plugins

3、重启，查看是否正常

三、升级jenkins版本，适配更新后的jenkins插件版本
