Like properties in the Java platform, environment variables are key/value pairs, where both the key and the value are strings. Many operating systems use environment variables to pass configuration information to applications. So if you don’t need a feature you can simple ignore the required plugin. The best thing that eclipse is cabable of is that it uses plugins for adding more features. Eclipse is the most common Integrated Development Environment (IDE) used by Java developers. Eclipse is managed and directed by the Consortium. IntroductionĮclipse is a Java-based open source platform that allows a software developer to create a customized development environment from plug-in components built by Eclipse members.
For this example we will make use of Eclipse Luna 4.4.2.
