post equivalent in scripted pipeline?

Question

What is the syntax of 'post' in scripted pipeline comparing to declarative pipeline? https://jenkins.io/doc/book/pipeline/syntax/#post

Answer 1

For scripted pipeline, everything must be written programmatically and most of the work is done in the finally block:

Jenkinsfile (Scripted Pipeline):

node {     try {         stage('Test') {             sh 'echo "Fail!"; exit 1'         }         echo 'This will run only if successful'     } catch (e) {         echo 'This will run only if failed'          // Since we're catching the exception in order to report on it,         // we need to re-throw it, to ensure that the build is marked as failed         throw e     } finally {         def currentResult = currentBuild.result ?: 'SUCCESS'         if (currentResult == 'UNSTABLE') {             echo 'This will run only if the run was marked as unstable'         }          def previousResult = currentBuild.getPreviousBuild()?.result         if (previousResult != null && previousResult != currentResult) {             echo 'This will run only if the state of the Pipeline has changed'             echo 'For example, if the Pipeline was previously failing but is now successful'         }          echo 'This will always run'     } }

You can modify @jf2010 solution by using closures so that it looks a little neater (in my opinion)

try {     pipeline() } catch (e) {     postFailure(e) } finally {     postAlways() }   def pipeline(){     stage('Test') {         sh 'echo "Fail!"; exit 1'     }     println 'This will run only if successful' }  def postFailure(e) {     println "Failed because of $e"     println 'This will run only if failed'  }  def postAlways() {     println 'This will always run' }
