Question

我厌倦了詹金斯窗口顶部的安全提示，告诉我升级我的插件，所以我升级了这些插件。当我重新启动时，熟悉的Jenkins登录页面被替换为以下堆栈跟踪：

除了恢复备份之外，还有什么办法可以从中恢复吗？我目前没有shell访问系统，所以请记住你的答案。

詹金斯版本：2.46.2

Splunk插件版本：1.3.1

Answer 1

我能够通过SSH访问系统并执行以下操作来解决我的问题。解决方案取自Removing and Disabling Plugins维基页面。

touch /var/lib/jenkins/plugins/splunk-devops.jpi.disabled
touch /var/lib/jenkins/plugins/splunk-devops-extend.jpi.disabled

然后，我重新启动了。从文档中，我认为任何插件都可以实现这一点。

升级Splunk插件后，Jenkins抛出NullPointerException
