How to skip a stage in Jenkinsfile pipeline when pipeline name ends with deliver?

Question

I have 2 pipelines one for review and one for deploy. So when the pipeline ends with review, I want to skip Jenkinsfile execution. However, when it ends with deploy, it should execute the stage or the Jenkinsfile.

I tried to use if, but this is a declarative pipeline, so when should be used. I want to avoid execution of stage using when condition if I encounter deploy pipeline end.

#!/usr/bin/env groovy
final boolean Deploy = (env.JOB_NAME as String).endsWith("-deploy")

    
pipeline {
    agent any
    parameters {
        choice(
            choices: ['greeting' , 'silence'],
            description: '',
            name: 'REQUESTED_ACTION')
    }

    stages {
//how to ouse when here to use deploy vairable to avoide execution of stage below
        stage ('Speak') {
            
            steps {
                echo "Hello, bitwiseman!"
            }
        }
    }
}

Answer 1

You can skip stages in declarative pipelines using when, so the following should work.

stages {
  stage('Deploy') {
    when { equals expected: true, actual: Deploy }
    steps {
      // ...
    }
  }
}

Answer 2

An alternative to @StephenKing’s answer, which is also correct, you can rewrite the when block when evaluating Booleans as follows:

stages {
    stage('Deploy') {
        when { 
            expression {
                return Deploy
            }
        }
        steps {
            echo "Hello, bitwiseman!" // Step executes only when Deploy is true

        }
    }
}

This will execute the stage Deploy only when the variable Deploy evaluates to true, else the stage will be skipped.
