插件更新后 Jenkins 严重错误

Question

我尝试更新几个我的 Jenkins 插件(不记得是哪个)但挂了。大约 15 分钟后，我决定重新启动 jenkins 服务器。这是我在 Jenkins 用户界面上得到的:

我尝试将 war 从 1.486 更新到 1.502，但行为没有变化。我该怎么做才能让 Jenkins 再次运行？

Answer 1

这是一个 known bug .

复制/粘贴以供引用:

Start 1.490 on a clean home dir, then ask to upgrade the Maven plugin to version 1.491, and restart. After the restart, there are linkage errors from the Maven plugin, predictably enough (since it is using 1.491+ core APIs); but all of Jenkins fails to start, making it impossible to use the GUI to back out the update. (Workaround: delete $JENKINS_HOME/plugins/maven-plugin.jpi.pinned.)
