如何在Jenkinsfile中捕获手动UI取消作业 [英] How to catch manual UI cancel of job in Jenkinsfile

问题描述

我试图找到有关如何在Jenkinsfile管道中捕获用户在jenkins Web UI中取消作业时发生的错误的文档.

I've tried to find documentation about how in a Jenkinsfile pipeline catching the error that occurs when a user cancels a job in jenkins web UI.

我没有使用post或try/catch/finally方法，它们仅在构建中出现故障时才起作用.

I haven't got the postor try/catch/finally approaches to work, they only work when something fails within the build.

这导致有人取消工作时无法释放资源.

This causes resources not to be free'd up when someone cancels a job.

我今天拥有的是声明性管道中的脚本，如下所示:

What I have today, is a script within a declarative pipeline, like so:

pipeline {
  stage("test") {
    steps {
      parallell (
        unit: {
          node("main-builder") {
            script {
              try { sh "<build stuff>" } catch (ex) { report } finally { cleanup }
            }
          }
        }
      )
    }
  }
}

因此，当从UI中手动取消作业时，将忽略catch(ex)和finally块中的所有内容.

So, everything within catch(ex) and finally blocks is ignored when a job is manually cancelled from the UI.

推荐答案

非声明性方法:

中止管道脚本生成时，将引发类型为org.jenkinsci.plugins.workflow.steps.FlowInterruptedException的异常.在catch块中释放资源，然后重新引发异常.

When you abort pipeline script build, exception of type org.jenkinsci.plugins.workflow.steps.FlowInterruptedException is thrown. Release resources in catch block and re-throw the exception.

import org.jenkinsci.plugins.workflow.steps.FlowInterruptedException

def releaseResources() {
    echo "Releasing resources"
    sleep 10
}

node {
    try {
        echo "Doing steps..."
        sleep 20
    } catch (FlowInterruptedException interruptEx) {
        releaseResources()
        throw interruptEx
    }
}

声明性方法:

相同，但在stage的steps中的script {}块内.不是最巧妙的解决方案，而是我已经测试并可以正常工作的解决方案.

The same, but within a script {} block in the steps of the stage. Not the neatest solution but the one that I've tested and got working.
