Eclipse + Java 8 support?

Question

How can I get Java 8 to work with Eclipse?

I have followed this guide but doesn't work. I've also seen the Eclipse Java 8 wiki page, but they don't explain what to do with the checked out git repositories.

For Kepler SR2 (4.3.2) a feature patch needs to be installed in order to get JAVA 8 support. Follow these steps:

• Eclipse - Help (MENU) > Install New Software...

• enter the following URL into the 'Work with' field:
  http://download.eclipse.org/eclipse/updates/4.3-P-builds/

• press 'Enter'
  

• select category 'Eclipse Java 8 Support (for Kepler SR2)'
  
• click 'Next'
  
• click 'Next'
  
• accept the license
• click 'Finish'
  
  
• restart Eclipse when asked

In order to have the desired JRE/ JDK on BuildPath, follow these steps.

• Right click on Project from Package Explorer
• Select BuildPath and then select Configure Builpath
• Select Libraries Tab from the popped up Properties window
• Select the current JRE System Library
• Click Remove button
• Click on Add Library button
• Select JRE System Library
• There you will be able to add your desired JRE/ JDK version using 3 different methods.

If you don't find your desired version of JRE/ JDK there in those 3 options, then you will have to install that first. The following link helps you in detail with screen shots to do the same. Hope it helps.
