Learning Continuous Integration with Jenkins

By: Nikhil Pathania

Overview of this book

In past few years, Agile software development has seen tremendous growth across the world. There is huge demand for software delivery solutions that are fast yet flexible to frequent amendments. As a result, CI and continuous delivery methodologies are gaining popularity. Jenkins’ core functionality and flexibility allows it to fit in a variety of environments and can help streamline the development process for all stakeholders. This book starts off by explaining the concepts of CI and its significance in the Agile world with a whole chapter dedicated to it. Next, you’ll learn to configure and set up Jenkins. You’ll gain a foothold in implementing CI and continuous delivery methods. We dive into the various features offered by Jenkins one by one exploiting them for CI. After that, you’ll find out how to use the built-in pipeline feature of Jenkins. You’ll see how to integrate Jenkins with code analysis tools and test automation tools in order to achieve continuous delivery. Next, you’ll be introduced to continuous deployment and learn to achieve it using Jenkins. Through this book’s wealth of best practices and real-world tips, you'll discover how easy it is to implement a CI service with Jenkins.

The Jenkins pipeline to poll the integration branch


This is the second pipeline of the two, both of which are part of the CI pipeline structure discussed in the previous chapter. This pipeline contains two Jenkins jobs. The first Jenkins job does the following tasks:

  • It polls the integration branch for changes at regular intervals

  • It executes the static code analysis

  • It performs a build on the modified code

  • It executes the integration tests

Creating a Jenkins job to poll, build, perform static code analysis, and integration tests

I assume you are logged in to Jenkins as an admin and have privileges to create and modify jobs. From the Jenkins Dashboard, follow these steps:

  1. Click on New Item.

  2. Name your new Jenkins job Poll_Build_StaticCodeAnalysis_IntegrationTest_Integration_Branch.

  3. Set the type of job as Freestyle project and click on OK to proceed.

Polling the version control system for changes using Jenkins

This is a critical step in which we connect Jenkins with the version control system. This...
