Extending Jenkins

Overview of this book

Jenkins CI is the leading open source continuous integration server. It is written in Java and has a wealth of plugins to support the building and testing of virtually any project. Jenkins supports multiple Software Configuration Management tools such as Git, Subversion, and Mercurial. This book explores and explains the many extension points and customizations that Jenkins offers its users, and teaches you how to develop your own Jenkins extensions and plugins. First, you will learn how to adapt Jenkins and leverage its abilities to empower DevOps, Continuous Integration, Continuous Deployment, and Agile projects. Next, you will find out how to reduce the cost of modern software development, increase the quality of deliveries, and thereby reduce the time to market. We will also teach you how to create your own custom plugins using Extension points. Finally, we will show you how to combine everything you learned over the course of the book into one real-world scenario.

Summary


In this chapter, we looked at the concepts behind several major design patterns and saw when you would use each approach and why you would do so.

If you are an experienced Java programmer, these concepts should be very familiar, and if not, then hopefully this will serve as a foundation that will help you to understand not only what we are doing in the subsequent chapters, but also why we are doing it.

In the beginning of this chapter, we touched upon the philosophy behind plugin development—that people should seek to collaborate, reuse, and extend existing code to provide new functionality whenever possible. If everyone went off and created their own plugins for their own particular needs, rather than collaborating and contributing to existing efforts, there would be massive duplication and replication, and the quality would be far poorer as a result.

This ethos and the preceding design approach has created a community of plugin developers who produce high quality software by providing...
