Eclipse/Installation

< Eclipse

Installing Eclipse is relatively easy, but does involve a few steps and software from at least two different sources. Eclipse is a Java-based application and, as such, requires a Java runtime environment (JRE) in order to run.

Install a JVM

Regardless of your operating system, you will need to install some Java virtual machine (JVM). You may either install a Java Runtime Environment (JRE), or a Java Development Kit (JDK), depending on what you want to do with Eclipse. If you intend to use Eclipse for Java development, then you should install a JDK (the JDK includes--among other useful things--the source code for the standard Java libraries). If you aren't planning to use Eclipse for Java development and want to save some disk space, install a JRE.

• If you're using Windows, you may already have a JRE installed, but upgrading won't hurt.
• If using Linux, read this
  • GCJ will NOT work.
  • Also see: Installing JRE 1.6.0 (Update x) as the Default Runtime in Linux.

JRE/JDK Sources

There are several sources for a JRE/JDK. Here are some of the more common/popular ones (listed alphabetically):

• IBM JDK
• OpenJDK
• Oracle JDK

Eclipse 4.2 (Juno)

Eclipse 4.2 (Juno) was released in June 2012.

A Java 6 JRE/JDK is recommended for Eclipse 4.2. More information concerning tested configurations for Eclipse 4.2 is provided here.

Download Eclipse from the Eclipse Downloads Page.

The download will be delivered as a compressed (i.e. a ".zip", or ".tar.gz") file. Decompress this file into the directory of your choice (e.g. "c:\Program Files\Eclipse" on Windows). You can optionally create a shortcut of the executable file ("eclipse.exe" on Windows, or "eclipse" on Linux).

Note that there is a known problem with the built-in decompression utility on all current versions of Windows. We recommend that you use a more robust decompression utility such as the open source 7zip when decompressing an Eclipse download. Some people report success when initially decompressing Eclipse into a root directory (e.g. c:\) and then moving it to a more appropriate home (e.g. c:\Program Files\Eclipse)

Extending Eclipse

Use the Help > Install new software... menu option to add Juno features to your Eclipse installation (you can, for example, use this option to add C/C++ development support). Additionally, you can tap into a vast collection of extensions provided by the Eclipse community and ecosystem via theEclipse Marketplace Client (Help > Eclipse Marketplace)
