Tutorial: InstallingEclipse on your Own Computer

By Jonathon Lundy and RonCytron

Eclipse is anIntegrated Development Environment, or IDE,which is software that provides all the essential tools you will need forediting, running, and debugging your Java programs.Eclipse and all of the supporting software is alreadyinstalled on CEC computers, but you may also wish to install it on your owncomputer, so that you are not limited to working only on CEC boxes.(It’sfree!)Versions of thesoftware are available for all operating systems.

I. Installing theJava Development Kit (JDK)

Note: Mac users skip to the last partof this section.

JavaSE Downloads, click theplain Java button, shown in the green box below, to download most recent updateof JDK 6.

Beware:The CEC computers are configured with JDK 6.

Mac Users: Mac OS X comes pre-installedwith JDK.To ensure that you haveJDK 6 support, download the appropriate updates from http://developer.apple.com/java/,where you can also read more about Java for Mac.

II. Installing andStarting Eclipse

Nowthat the Java JDK has been installed, we can now download and run the EclipseIDE.First, point your browser to http://www.eclipse.org/downloads/.Then, under the Eclipse Packages tab, find the listing for Eclipse IDE for Java Developers.Select your OS and download the appropriate archive file.

Whenthe download is finished, extract the archive to a new folder for Eclipse in aplace of your choosing (you’ll probably want to put it in whatever folderapplications are usually stored on your OS).No further installation is required.You may wish to create a shortcut tothe Eclipse executable to place on your desktop/dock so you don’t have to findthe folder you installed it to each time you wish to start Eclipse.

StartEclipse.(Note that startup cantake a while!)You will beprompted during startup to select a folder for your workspace, which is whereyour Java files are stored locally.Select a folder (preferably an empty one) to use as your workspace.The default is usually a goodchoice.Select Use this as the default and do not ask againif you don’t want to be asked this question every time on start-up.

OnceEclipse has started, you’ll be taken to the Welcome tab.Close this tab to go to the defaultEclipse perspective.

III. Installingthe Subversive Plug-in

Subversiveis a plug-in for Eclipse that allows Eclipse to use Subversion (SVN),which is a versioncontrol system.Use of thissystem will make it easy for you to easily move from your own computer to a CECcomputer, work in groups, and electronically submit your work.However, Eclipse does not support SVNout of the box; a plug-in is required to make it work.
