  <p>In my jenkins file I have this sample pipeline</p>
  
  <pre><code>pipeline {
      agent any
  
      stages {
          stage('Build') {
              steps {
                  echo 'Building..'
             }
          }
          stage('Test') {
              steps {
                echo 'Testing..'
              }
          }
          stage('Deploy') {
              steps {
                  echo 'Deploying....'
              }
          }
      }
  }
