Continuous integration (CI) with automated test execution has been widely adopted in recent years. The concept behind CI has changed how companies look at Build Management, Release Management, Deployment Automation, and Test Orchestration. Hudson is a CI solution that provides executives, business managers, software developers, and architects with a better sense of the development progress and code quality of projects throughout their development life cycle.A fast-paced and hands-on introduction to the key features of Hudson 3. You will be introduced to tools that can be used to improve the quality of software development projects. You will also learn how to install and secure Hudson in a variety of IT environments. Staring with a brief introduction to Hudson and how it helps many IT organizations deliver high quality software, Hudson 3 Essentials will show you how Hudson can be installed and deployed in various environments. You will also be guided through the different methods of securing your Hudson installation. Moving on from the basics, you will be introduced to several important Hudson plugins and learn how to extend its functionality by developing your own plugins. You will be shown how Hudson can be used to build different types of applications and how it can deploy a web application to an application server. Finally, you will discover how Hudson can be used to perform automated testing on software applications, and how to generate reports that describe the results.

Environment variables

An environment variable is a variable that stores a value that is used by an operating system or a process (application).

In this book, I will use Unix-style environment variables in examples. If you are using Windows, simply replace ${MY_VARIABLE} with %MY_VARIABLE%.

The method of setting environment variables is operating system dependent, but the format of creating and modifying environment variables is similar.

As an example, we will show how to add the JAVA_HOME environment variable on both Linux and Windows operating systems. This example assumes that the JDK has been installed to ${HOME}/jdk1.7.0_25 on Linux and to C:\jdk1.7.0_25 on Windows.


These are not appropriate installation locations for production systems; they are just intended to be used for experimentation and prototyping.

To set the JAVA_HOME environment variable in a Linux system that uses the bash shell, add the following lines to the ${HOME}/.bashrc file:

export JAVA_HOME=${HOME}/jdk1.7.0_25
