Lesson: Installing Eclipse

Installation procedure for Eclipse and the leJOS plugin for Eclipse.

Install the Eclipse IDE and the leJOS plugin for Eclipse.

If you do not already have a working Eclipse IDE, you should download Eclipse here. The recommended package of Eclipse is the Eclipse IDE for Java Developers. Install the 32 or 64 bit version matching the bitness of your PC. Eclipse requires Java Run Time (JRE) 8 (1.8) in 32 or 64 bit form matching the bitness of Eclipse. Download here if you do not already have it. 
Eclipse is delivered in a .zip file. To install, simply unzip to any directory you wish, though Program Files is a good place. To run Eclipse, double click the executable file. It is best to create a shortcut to the executable file and place the shortcut on your desktop. Eclipse does not modify the Windows registry. To delete Eclipse, simply delete the Eclipse directory.
The first time you run Eclipse it will prompt you for a workspace location. It is probably best to go with the default shown in the prompt. The workspace is a directory where your Java projects will be stored.
It is best to configure Eclipse to automatically search for updates. On the Eclipse menu bar, click Window -> Preferences. Double click Install/Update in the Preferences list. Highlight Automatic Updates. Check the option to Automatically find new Updates and Notify me. Click Ok. This will keep Eclipse and the leJOS plugin updated.
Once Eclipse is installed, you should install the leJOS plugin for Eclipse. Instructions are found here. Note: the repository URL for the plugin in the instructions is incorrect. Use http://www.lejos.org/tools/eclipse/plugin/ev3/ instead.
