java - How do I add execution environment 1.8 to Eclipse Luna?

Question

I have jre8 installed and set as the default for the jre but under compiler compliance I can't find 1.8 and under execution environment I can't find javaSE 1.8. I'm using the latest build of Eclipse EE.

I took a look at this manual http://help.eclipse.org/luna/index.jsp?topic=%2Forg.eclipse.jdt.doc.user%2Ftasks%2Ftask-add_new_jre.htm But I couldn't find any .ee files in my jre8 or JDK1.8 installation directories.

Open Preferences and look in 'Java > Installed JREs'. If you don't have a Java 8 shown there click 'Add...' to add it. Close the preferences.

Open Preferences again and look in 'Java > Installed JREs > Execution Environments', select 'JavaSE-1.8' and make sure your Java 1.8 is checked as the Compatible JRE
