jenkins notifying error occured in different steps by sending mail in Pipeline (former known as Workflow)

Question

I have a pipeline with multiple steps, for example:

stage \'dev - compile\'
node(\'master\') {
  //do something
}

stage \'test- compile\'
node(\'master\') {         


        

Answer 1

What I did to include useful information in my mail about the failure:

try {
    stage 'checkout cvs'
    node('master') {
        /** CODE **/
    }

    stage 'compile'
    node('master') {
        /** CODE **/
    }

    stage 'test unit'
    node('master') {
        /** CODE **/
    }   

    stage 'package'
    node('master') {
        /** CODE **/
    }

    stage 'nexus publish'
    node('master') {
        /** CODE **/
    }

    stage 'Deploy to App Server'
    node('master') {
        /** CODE **/            
    }

} catch(e) {
    String error = "${e}";
    // Make the string with job info, example:
    // ${env.JOB_NAME}
    // ${env.BUILD_NUMBER} 
    // ${env.BUILD_URL}
    // and other variables in the code
    mail bcc: '',
         cc: '',
         charset: 'UTF-8',
         from: '',
         mimeType: 'text/html',
         replyTo: '',
         subject: "ERROR CI: Project name -> ${env.JOB_NAME}",
         to: "${mails_to_notify}",
         body: "${pivote}
\n\nMensaje de error: ${error}\n\n
Projecto: ${env.JOB_NAME} 
Build Number: ${env.BUILD_NUMBER} 
 URL de build: ${env.BUILD_URL}";
    error "${error}"
}
