通过在管道中发送邮件（以前称为工作流），jenkins通知错误发生在不同的步骤中

我做了什么以便在邮件中包含有关失败的有用信息：

try {    stage 'checkout cvs'    node('master') {            }    stage 'compile'    node('master') {            }    stage 'test unit'    node('master') {            }    stage 'package'    node('master') {            }    stage 'nexus publish'    node('master') {            }    stage 'Deploy to App Server'    node('master') {             }} 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 pre    mail bcc: '',         cc: '',         charset: 'UTF-8',         from: '',         mimeType: 'text/html',         replyTo: '',         subject: "ERROR CI: Project name -> ${env.JOB_NAME}",         to: "${mails_to_notify}",         body: "<b>${pivote}</b><br>nnMensaje de error: ${error}nn<br>Projecto: ${env.JOB_NAME} <br>Build Number: ${env.BUILD_NUMBER} <br> URL de build: ${env.BUILD_URL}";    error "${error}"}
