Send email on jenkins pipeline failure

Question

How can i add to a jenkins pipeline an old-style post-build task which sends email when the build fails? I cannot find \"Post-build actions\" in the GUI for a pipeline. I know t

Answer 1

For taking action only when build status has changed you can use the post > changed block.

And for checking, what state the status has changed to you can use the script block in combination with checking the value of currentBuild.currentResult property.

Like so:

pipeline {
    ...

    post {
        changed {
            script {
                if (currentBuild.currentResult == 'FAILURE') { // Other values: SUCCESS, UNSTABLE
                    // Send an email only if the build status has changed from green/unstable to red
                    emailext subject: '$DEFAULT_SUBJECT',
                        body: '$DEFAULT_CONTENT',
                        recipientProviders: [
                            [$class: 'CulpritsRecipientProvider'],
                            [$class: 'DevelopersRecipientProvider'],
                            [$class: 'RequesterRecipientProvider']
                        ], 
                        replyTo: '$DEFAULT_REPLYTO',
                        to: '$DEFAULT_RECIPIENTS'
                }
            }
        }
    }

}
