更新插件角色策略插件后，jenkins 不工作

Question

我正在使用jenkins2.138.1。我在“管理插件”部分更新了基于角色的策略，并尝试使用jenkinsurl/restart. 它抛出以下错误，现在看不到登录屏幕：

Answer 1

遇到同样的问题，解决方法如下：

我关闭了 jenkins url 因为这使它可用但每个人都成为管理员

备份 config.xml，因为它将被清空。

在$JENKINS_HOME/config.xml注释掉/删除所有authorizationStrategy块并更改<useSecurity>true</useSecurity>为false。

启动 jenkins（它正常启动但没有身份验证。

将 config.xml 更改为以前的原始版本（包括以前运行的所有安全性），并在原始角色策略配置到位的情况下正常工作。
