How set Jenkins to send email when Pipeline is broken

Question

In Jenkins pipeline I have (using Extended Email plugin):

#!/usr/bin/env groovy

pipeline {

    agent any

    stages {
        stage('install') {
            steps {
                echo 'install...'
            }
        }
    }

    post {  
        failure {  
            emailext body: 'fail', subject: 'failed', to: '[email protected]'
        }  
        // always {}
    } 
}

When build fails it sends email. However, I want to send email also, when the pipeline syntax is broken itself, eg. if you uncomment the always {} line above, you get:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 69: No steps specified for branch @ line 69, column 17.
            always {  
                   ^

however, that build fails silently (bcz syntax issue). How to get emails on such cases too?

Answer 1

You can't do that if your post stages syntax is incorrect. But, if the body pipeline has an error and the post stage is error-free, it sends the email. For example, this works:

#!/usr/bin/env groovy

pipeline {

    agent any

    stages {
        stage('install') {
            steps {
                eeecho_this_is_a_typo 'install...'
            }
        }
    }

    post {  
        failure {  
            emailext body: 'fail', subject: 'failed', to: '[email protected]'
        }  
    } 
}
