Jenkins input on declarative pipeline

Question

may I ask if it is do-able if I can get the user input and run a script based on what was chosen by the user? the logic whould be

IF User choose Proceed THEN run a script (in my case promote or Blue/Green deployment) IF User choose Abort THEN don't terminate the jenkins job, run a script (in my case rollback)

This is the script I'm using however I have no idea how to apply after validate stage

  pipeline {
  agent any

  stages {
    stage('Deploy') {
      steps {
        sh """#!/bin/bash +x
          echo "performing sts assume role"
          //SCRIPT-HERE//        
          echo "performing ansible deploy"
          //SCRIPT-HERE//  
        """
      }
    }
    stage('validate') {
        steps {

            timeout(30) {
                script {
                    input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')
                }
            }
        }
    }
  }

}

One more issue I'm seeing is, although this pipeline script is running, The Proceed / Abort is not clickable on the jenkins job Console output, is it a bug? I'm referring to the image shown below

I was able to add nandilov's suggestion however it seems that the logic is still not applying, please advise on what is missed here

pipeline {
  agent any

  stages {
    stage('Deploy') {
      steps {
        sh """#!/bin/bash +x
          echo "performing sts assume role"

          echo "performing ansible deploy"

        """
      }
    }
    stage('validate') {
        steps {
          script {
            env.flagError = "false"
              try {
              input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')

              }catch(e){
                println "input aborted or timeout expired, will try to rollback."
                env.flagError = "true"        
              }
          }
        }
    }

    stage("If user selects Proceed"){
        when{
            expression { env.inputValue == "value1" }
        }
        steps{
            sh """#!/bin/bash +x
              echo "User selected proceed"
            """
        }
    }

    stage("rollback if flag error true"){
        when{
            expression { env.inputValue == "value2" }
        }
        steps{
            sh """#!/bin/bash +x
              echo "User selected Abort"
            """
        }
    }

  }

}

from the pipeline view it never triggered either one of the last two stages when choosing "Abort" or "Proceed"

These are the logs when choosing Abort or Proceed

Answer 1

If you want to have the job aborted and do something, you can try/catch it:

try{
    input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')
}catch(e){
    println "input aborted or timeout expired, will try to rollback."
    // execute rollback
}

You also can do it in another stage:

pipeline {
  agent any

  stages {
    stage('Deploy') {
      steps {
        sh """#!/bin/bash +x
          echo "performing sts assume role"

          echo "performing ansible deploy"

        """
      }
    }
    stage('validate') {
        steps {
          script {
            env.flagError = "false"
              try {
              input(message: 'Please validate, this job will automatically ABORTED after 30 minutes even if no user input provided', ok: 'Proceed')

              }catch(e){
                println "input aborted or timeout expired, will try to rollback."
                env.flagError = "true"        
              }
          }
        }
    }

    stage("If user selects Proceed"){
        when{
            expression { env.flagError == "false" }
        }
        steps{
            sh """#!/bin/bash +x
              echo "User selected proceed"
            """
        }
    }

    stage("rollback if flag error true"){
        when{
            expression { env.flagError == "true" }
        }
        steps{
            sh """#!/bin/bash +x
              echo "User selected Abort"
            """
        }
    }

  }
