Issues:

Configure Eclipse (Windows only)

On Windows, you will need to configure Eclipse to use the Java Development Kit (JDK).
First, download and install JDK 6 from the Java web site.
Take note of where the Java installation ended up; we will use "C:\Program Files\Java\jdk1.6.0_20" below, though your path is likely to be different.
Also take note of the path to your Eclipse installation; we will use "C:\Users\you\Programs\eclipse" though your path is likely to be different.
Open the file "C:\Users\you\Programs\eclipse\eclipse.ini" in a text editor, and follow these instructions to specify the JVM using the "-vm" flag. Be careful to follow the instructions exactly.
Now update Eclipse's JRE to be JDK-aware:

• Launch Eclipse
• From the menu choose Window > Preferences
• Select Java > Installed JREs
• Click Search..., navigate to "C:\Program Files\Java\jdk1.6.0_20" and click OK
• Check the box next to the JDK that appears and click OK 

Edit eclipse.ini:

plugins/org.eclipse.equinox.launcher_1.3.0.v20120522-1813.jar
--launcher.library
