To create folders and subfolders in Jenkins using pipeline code, you can use Jenkins Job DSL or Groovy script. Here’s how you can accomplish this in a Jenkins pipeline:

Using Jenkins Job DSL

The Jenkins Job DSL plugin allows you to define jobs and folders programmatically. Here’s an example of how to create a folder and subfolder using Job DSL in a pipeline script:

pipeline {
    agent any

    stages {
        stage('Create Folders') {
            steps {
                script {
                    // Using Job DSL to create folders
                    jobDsl scriptText: '''
                    folder('MainFolder') {
                        displayName('Main Folder')
                        description('This is the main folder')
                    }

                    folder('MainFolder/SubFolder') {
                        displayName('Sub Folder')
                        description('This is a subfolder inside Main Folder')
                    }
                    '''
                }
            }
        }
    }
}Code language: PHP (php)

Explanation

1.  pipeline: This defines a Jenkins pipeline script.
2.  agent any: This specifies that the pipeline can run on any available agent.
3.  stages: The pipeline consists of stages, and each stage contains steps to execute.
4.  script: The script block is used to execute Groovy code.
5.  jobDsl: The jobDsl step is used to execute Job DSL scripts, which create and configure Jenkins jobs and folders.
6.  folder(): The folder() method is used to define a folder. You specify the folder path, and optional display name and description.

Using Jenkins Groovy Script

import jenkins.model.*
import com.cloudbees.hudson.plugins.folder.*

// Function to create a folder
def createFolder(folderName, parentFolder = null) {
    def jenkins = Jenkins.instance
    def folder
    if (parentFolder) {
        folder = parentFolder.getItem(folderName)
    } else {
        folder = jenkins.getItem(folderName)
    }
    
    if (folder == null) {
        def folderDescriptor = jenkins.getDescriptorByType(Folder.DescriptorImpl.class)
        folder = folderDescriptor.newInstance(jenkins, folderName)
        if (parentFolder) {
            parentFolder.add(folder, folderName)
        } else {
            jenkins.add(folder, folderName)
        }
        println("Folder '${folderName}' created successfully.")
    } else {
        println("Folder '${folderName}' already exists.")
    }
    return folder
}

node {
    stage('Create Folders') {
        // Create a top-level folder
        def mainFolder = createFolder('MainFolder')

        // Create a subfolder inside the main folder
        createFolder('SubFolder', mainFolder)
    }
}Code language: JavaScript (javascript)

Explanation

•   Imports: Import Jenkins and Folder classes to interact with Jenkins and create folders.
•   createFolder Function: This function checks if a folder already exists and creates it if it doesn’t. It can create both top-level folders and subfolders.
•   Jenkins API: The script uses the Jenkins API to create folders programmatically.Code language: JavaScript (javascript)

Usage

•   Job DSL Plugin: If using the Job DSL method, ensure the Jenkins Job DSL plugin is installed and enabled.
•   Permissions: Ensure that the Jenkins user executing the script has the necessary permissions to create folders.
•   Execution: You can execute these scripts as part of a Jenkins pipeline job to automate folder management.Code language: JavaScript (javascript)
