What Is Jenkins Scripting?


Scott Campbell

Jenkins is a popular open-source automation server that is widely used for continuous integration and continuous delivery (CI/CD) pipelines. With Jenkins, you can automate various tasks related to building, testing, and deploying software projects. One of the key features that makes Jenkins so powerful and versatile is its support for scripting.

What Is Jenkins Scripting?

Jenkins scripting refers to the ability to write custom scripts that can be executed within Jenkins to perform specific tasks or automate processes. These scripts are written in different programming languages, such as Groovy, Shell, Python, or even plain old Batch scripts.

Why Use Jenkins Scripting?

Jenkins scripting opens up a world of possibilities when it comes to automating your CI/CD pipelines. It allows you to define complex workflows, customize build steps, integrate with external tools and services, and perform actions based on various conditions.

By leveraging Jenkins scripting capabilities, you can:

  • Automate Build Processes: With scripts, you can define the steps required to build your software projects from source code. This includes tasks like compiling code, running unit tests, generating documentation, creating artifacts, and more.
  • Manage Dependencies: Scripts enable you to handle dependencies between different components of your project. You can automatically download and install libraries or tools required for the build process.
  • Perform Code Quality Checks: By integrating code analysis tools into your scripts, you can automatically run static code analysis or code formatting checks during the build process.

    This helps maintain code quality standards across your projects.

  • Deploy Applications: Scripts allow you to define deployment steps for deploying your applications to different environments or servers. This includes tasks like copying files, configuring servers, starting services, etc.
  • Notification and Reporting: You can use scripts to send notifications or generate reports based on the build status or specific events. This keeps your team informed about the progress and results of the build process.

How to Use Jenkins Scripting?

Jenkins provides a dedicated interface for managing and executing scripts. Here’s a high-level overview of how you can use Jenkins scripting:

Step 1: Install Required Plugins

Before you start using Jenkins scripting, make sure you have installed any required plugins for the specific scripting language you plan to use. Jenkins has a vast plugin ecosystem, allowing you to extend its functionality as per your needs.

Step 2: Create a New Jenkins Job

To start using scripting in Jenkins, create a new job by navigating to the Jenkins dashboard and clicking on “New Item”. Give your job a meaningful name and select the appropriate job type depending on your project requirements.

Step 3: Configure Build Steps

Within your job configuration, you can define multiple build steps that execute scripts. These steps can be sequential or parallel, depending on your workflow. For each step, specify the script location (either inline within the job configuration or from an external file) and choose the appropriate interpreter based on the script’s programming language.

Step 4: Customize Jenkins Environment

Jenkins provides various environment variables that can be accessed within your scripts. These variables contain useful information about the current build, such as project name, build number, workspace path, etc. You can leverage these variables to make your scripts more dynamic and adaptable.

Step 5: Execute Your Job

Once you have configured all the necessary steps and settings, save your job configuration and trigger a build either manually or automatically based on specific events (such as code changes or time-based triggers). Jenkins will then execute your scripts and provide real-time feedback on the build status.


Jenkins scripting is a powerful feature that empowers developers and DevOps teams to automate their CI/CD pipelines effectively. By harnessing the capabilities of scripting, you can streamline your software development processes, increase efficiency, and ensure consistent and reliable builds. So go ahead, explore Jenkins scripting, and unlock the full potential of automation in your software projects.
