Jenkins 声明性管道因 NullPointerException 而失败

Question

我不知道为什么我所有的管道突然都停止工作了。现在每次管道运行时，都会出现此错误

这是我创建的示例管道，用于测试即使是最简单的管道也确实会发生这种情况

pipeline {
    agent any
    
    options {
        disableConcurrentBuilds()
    }
    
    stages {
        stage('Test') {
            steps {
                sh 'echo WTF'
            }
        }
    }
}

我最近更新了所有可用的插件。这可能是问题的根源吗？

Answer 1

我想您需要将 Jenkins 设置的 configure system 中的管道持久性设置更改为 performance-optimized(clean shutdown)。

Answer 2

事实证明，这是由于其中一个插件的更新所致。我不确定是哪个插件导致了这个问题，但我所做的是在 Jenkins 运行 on:

的机器上使用这个命令

ls -alt *.hpi *.jpi

这应该会列出所有已安装的插件及其安装日期。通过将此命令返回的名称复制并粘贴到 google，您将能够找到完整的插件名称并能够使用 Jenkins GUI 将其恢复到以前的版本。
