<p>In agile development practices, developers need to integrate their work frequently to fix bugs or to create a new feature or functionality. To integrate all work efficiently and verify it is an error-prone and time-consuming manual task. Jenkins is used specifically for continuous integration, helping to enforce the principles of agile development.</p> <p>This book begins by tackling the installation of the necessary software dependencies and libraries you'll need to perform continuous integration for a Java application. From there, you'll integrate code repositories, applications, and build tools for the implementation of continuous integration. Finally, you'll explore the automated deployment of an application in Tomcat, along with details on managing and configuring Jenkins based on your requirements by using plugins.</p>
