Here's a simple Jenkins pipeline script that echoes "Hello World":

pipeline {
    agent any

    stages {
        stage('Hello World') {
            steps {
                echo 'Hello World!'
            }
        }
    }
}

Let me explain what each part does:

• pipeline { ... }: Defines the pipeline.
• agent any: Specifies that the pipeline can run on any available agent.
• stages { ... }: Defines the stages of the pipeline.
• stage('Hello World') { ... }: Defines a stage named "Hello World".
• steps { ... }: Defines the steps within the stage.
• echo 'Hello World!': Prints "Hello World!" to the console.

To use this script in Jenkins:

1. Create a new Jenkins job.
2. Choose "Pipeline" as the job type.# hack
