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.

Eclipse and Mylyn

The first and probably by far the most popular of all the development IDEs that we will look at is the Eclipse platform—this is extremely popular for a number of different projects including Java, C/C++, and PHP, and it has a vast user base and a wealth of mature and easily available plugins.

To achieve our goal of presenting Jenkins information to developers, Mylyn is currently the most popular extension that we can use in conjunction with Eclipse.

There is more information on Mylyn and the many features it provides at this link:

http://www.eclipse.org/mylyn/

The documentation at this link also states that Mylyn reduces information overload and makes multitasking easy, which sounds exactly like what we are looking for!
