Jenkins管道构建失败后如何发送Slack通知？ [英] How to send Slack notification after Jenkins pipeline build failed?

问题描述

在Jenkins v2.19中我有一个管道groovy脚本。此外，我还有一个

Slack Notification Pluginv2.0.1和Groovy Postbuild Plugin。

我已成功发送消息build started 和构建完成（如果有的话）。

当某个构建步骤失败时 - 如何向Slack频道发送构建失败消息？ p>

解决方案

你可以做这样的事情，并使用try catch块。

以下是一些示例代码：

 节点{
尝试{
 notifyBuild（'STARTED'）
 
 stage（'Prepare code'）{
 echo'do checkout stuff'
} 
 
 stage（'Testing'）{
 echo '测试'
 echo'测试 - 发布覆盖结果'
} 
 
 stage（'Staging'）{
 echo'Deploy Stage'
} 
 
 stage（'Deploy'）{
 echo'Deploy  -  Backend'
 echo'Deploy  -  Frontend'
} 
 
} catch（e）{
 //如果抛出异常，构建失败
 currentBuild.result =FAILED
 throw e 
} finally {
 //成功或失败，总是发送通知
 notifyBuild（currentBuild.result）
} 
} 
 $ b $ def notifyBuild（String buildStatus ='STARTED'）{
 //建立null状态表示成功
 buildStatus = buildStatus？：'SUCCESSFUL'
 
 //默认值
 def colorName ='RED'
 def colorCode ='＃FF0000'
 def subject =$ {buildStatus}：作业'$ {env.JOB_NAME} [$ { env.BUILD_NUMBER}]'
 def summary =$ {subject}（$ {env.BUILD_URL}）
 
 //根据构建状态覆盖默认值
 if （buildStatus =='STARTED'）{
 color ='YELLOW'
 colorCode ='＃FFFF00'
} else if（buildStatus =='SUCCESSFUL'）{
 color = '绿色' 
 colorCode ='＃00FF00'
} else {
 color ='RED'
 colorCode ='＃FF0000'
} 
 
 / /发送通知
 slackSend（color：colorCode，message：summary）
}

I have a pipeline groovy script in Jenkins v2.19. Also I have a
"Slack Notification Plugin" v2.0.1 and "Groovy Postbuild Plugin".

I have successfully send a message "build started" and "build finished" (if it had).

When some build step failed – how I can send a message "Build failed" to the Slack channel?

解决方案

You could do something like this and use a try catch block.

Here is some example Code:

node {
    try {
        notifyBuild('STARTED')

        stage('Prepare code') {
            echo 'do checkout stuff'
        }

        stage('Testing') {
            echo 'Testing'
            echo 'Testing - publish coverage results'
        }

        stage('Staging') {
            echo 'Deploy Stage'
        }

        stage('Deploy') {
            echo 'Deploy - Backend'
            echo 'Deploy - Frontend'
        }

  } catch (e) {
    // If there was an exception thrown, the build failed
    currentBuild.result = "FAILED"
    throw e
  } finally {
    // Success or failure, always send notifications
    notifyBuild(currentBuild.result)
  }
}

def notifyBuild(String buildStatus = 'STARTED') {
  // build status of null means successful
  buildStatus =  buildStatus ?: 'SUCCESSFUL'

  // Default values
  def colorName = 'RED'
  def colorCode = '#FF0000'
  def subject = "${buildStatus}: Job '${env.JOB_NAME} [${env.BUILD_NUMBER}]'"
  def summary = "${subject} (${env.BUILD_URL})"

  // Override default values based on build status
  if (buildStatus == 'STARTED') {
    color = 'YELLOW'
    colorCode = '#FFFF00'
  } else if (buildStatus == 'SUCCESSFUL') {
    color = 'GREEN'
    colorCode = '#00FF00'
  } else {
    color = 'RED'
    colorCode = '#FF0000'
  }

  // Send notifications
  slackSend (color: colorCode, message: summary)
}
