Jenkins Scripted Pipelines
Start course
1h 47m

This course introduces you to Jenkins, a popular open-source tool used to perform Continuous Integration and Continuous Delivery.

We review the key Jenkins features and associated terminology. We then take you through a deep dive in configuring Jenkins to perform automated builds using the Jenkins web administration console in hands-on demonstrations, familiarising you with Jenkins and how to administer it. We’ll demonstrate features such as:

  • Installing and setting up Jenkins
  • Creating and configuring pipelines manually
  • Creating and configuring pipelines using a Jenkinsfile
  • Triggering build pipelines, manually and automatically
  • Navigating downstream and upstream build projects
  • Connecting to version control repositories such as GitHub
  • Setting up build pipelines for Java-based projects using Gradle
  • Recording artifacts and test results

Learning Objectives

What you'll learn:

  • The basic principles of build automation as implemented within Jenkins and how they should be applied to manage and maintain building, testing, and deploying your own enterprise software projects
  • How to install, set up, and configure Jenkins pipelines
  • The key differences between Jenkins declarative and scripted pipelines
  • How to manage build artifacts and test results
  • How to integrate and leverage third-party build tools like Gradle, Maven, Yarn, Webpack, and many more within a Jenkins pipeline


This training course provides many hands-on demonstrations where you will observe first hand how to use Jenkins to build and release different types of software projects, for example:

  • Building a front-end application which has been developed using the React Javascript framework, using technologies such as Webpack and Yarn
  • Building a back-end application developed using Java, Gradle, and Docker, requiring Jenkins to compile the source code, packaging it into a WebArchive file, and then finally releasing it into a Tomcat-based Docker image complete with Splunk-based instrumentation for logging and monitoring


  • A basic understanding of CICD, or Continuous Integration and Continuous Delivery
  • A basic understanding of software development and the software development life cycle
  • A basic understanding of version control and associated workflows

Intended Audience

  • Software Build and Release Engineers
  • Software Developers
  • DevOps Practitioners


The following GitHub repo contains sample Jenkins configurations used within the provided demonstrations:

- [Instructor] Welcome back! In this lecture, we'll introduce you to the Jenkins scripted pipelines syntax. 

The scripted pipeline syntax caters for a freestyle coded approach, meaning that it is a lot more flexible than its counterpart, and therefore is suited towards complex pipeline development, but for which requires you to be more knowledgeable coding wise. 

Okay, let's begin. The scripted pipeline structure looks like the following. Key points of the scripted syntax are: the syntax uses a programmatic or coding style to provide a high degree of flexibility and customization, the syntax uses Groovy as the scripting language, and the script typically starts with the node keyword to indicate that it is a scripted pipeline. 

Okay, let's now take a closer look at a couple of more in-depth examples using the scripted pipeline syntax. In this first example, you should be able to quickly see and appreciate the flexibility and expressiveness that the scripted syntax provides. 

Key points of this scripted pipeline example are: the ability to encapsulate complex logic into helper methods, the ability to define variables and assign and update their values, the ability use control flow statements to control build logic, and seeing that exception handling is possible using try catch blocks, enabling recovery from non-fatal build errors. The next scripted example is used to illustrate not so much how to build a particular flavor of technology such as Java versus .Net, but instead how to manage the Jenkins build environment itself. In this case it highlights how to setup an external workspace, which is then shared by two different nodes within the same pipeline execution. 

Key points of this scripted pipeline example are: multiple different labeled nodes are used, a shared external workspace is used, the first node builds the project using Maven, and the second node then performs testing within a try catch block reusing the same workspace. 

Okay, go ahead and close this lecture and we'll see you shortly in the next one, where you're provided with further hands on demonstrations showing you how to set up, configure, execute, and troubleshoot build pipelines.
