Jenkins Pipeline：中止一个阶段中的输入不能触发该阶段的中止后操作答案

【问题标题】：Jenkins Pipeline: abort an input in a stage cannot trigger the aborted post action of that stageJenkins Pipeline：中止一个阶段中的输入不能触发该阶段的中止后操作

【问题描述】：

我的目的很简单，只是想在用户在该阶段的输入步骤中单击“中止”按钮时在该阶段执行一些发布操作。我从 jenkins.io 阅读了一些文档，发现使用 post 指令似乎有一种隐含的方式来做到这一点。所以我在下面做了一些简单的测试：

首先是这样的：

pipeline {
    agent any
    stages {
        stage('test') {
            input {
                message 'Proceed?'
                ok 'yes'
                submitter 'admin'
            }
            steps {
                echo "helloworld"
            }
            post {
                aborted {
                    echo "stage test has been aborted"
                }
            }            
        }
    }
    post {
        aborted {
            echo "pipeline has been aborted"
        }
    }
}

如果我点击 Abort 按钮，日志输出只会显示：

[Pipeline] {
[Pipeline] stage
[Pipeline] { (test)
[Pipeline] input
Proceed?
yes or Abort
Aborted by admin
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] echo
pipeline has been aborted
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Rejected by SYSTEM
Finished: ABORTED

这意味着输入中止仅触发管道的后操作部分，而不是该阶段内的部分。然后我尝试另一个：

pipeline {
    agent any
    stages {
        stage('test') {            
            steps {
                sh "sleep 15"
            }
            post {
                aborted {
                    echo "stage test has been aborted"
                }
            }            
        }
    }
    post {
        aborted {
            echo "pipeline has been aborted"
        }
    }
}

我在 15 秒内中止此作业，输出将显示

[Pipeline] { (hide)
[Pipeline] stage
[Pipeline] { (test)
[Pipeline] sh
+ sleep 15
Sending interrupt signal to process
Aborted by admin
Terminated
script returned exit code 143
Post stage
[Pipeline] echo
stage test has been aborted
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] echo
pipeline has been aborted
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Finished: ABORTED

这意味着可以触发阶段中中止后的动作部分。

在一个阶段中中止输入步骤时，我如何执行一些发布操作，而不是整个管道？

我想我弄清楚以上两个示例之间的区别以及如何自己解决这个问题:)。

似乎只有在相关 Steps 部分的 currentResult 匹配但不匹配上面的 Input 部分时才会触发阶段中的 Post 操作。所以我做了一点改变，它起作用了。即让 Input 部分成为 Steps 部分中的脚本。

pipeline {
    agent any
    stages {
        stage('test') {
            steps {
                script {
                    input message: 'Proceed?', ok: 'Yes', submitter: 'admin'
                }
                echo "helloworld"
            }
            post {
                aborted{
                    echo "test stage has been aborted"
                }
            }            
        }
    }
    post {
        aborted {
            echo "pipeline has been aborted"
        }
    }
}

当点击Abort按钮时，输出日志为：

[Pipeline] Start of Pipeline
[Pipeline] node
Running on Jenkins in /var/jenkins_home/workspace/pipeline-demo
[Pipeline] {
[Pipeline] stage
[Pipeline] { (test)
[Pipeline] script
[Pipeline] {
[Pipeline] input
Proceed?
Yes or Abort
[Pipeline] }
[Pipeline] // script
Post stage
[Pipeline] echo
test stage has been aborted
[Pipeline] }
[Pipeline] // stage
[Pipeline] stage
[Pipeline] { (Declarative: Post Actions)
[Pipeline] echo
pipeline has been aborted
[Pipeline] }
[Pipeline] // stage
[Pipeline] }
[Pipeline] // node
[Pipeline] End of Pipeline
Rejected by admin
Finished: ABORTED

这让我很满意:)。我现在可以通过用户确认和自动回滚来组成一个复杂的管道。希望对你也有帮助。
