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.
A Java 11 JRE is recognized by Eclipse for launching. It can be added from the Window > Preferences > Java > Installed JREs > Add... page. It can also be added from the Package Explorer using the project's context menu.
Execution environments (EEs) are symbolic representations of JREs. For example, rather than talking about a specific JRE, with a specific name at a specific location on your disk, you can talk about the J2SE-1.4 execution environment.
Java 8 is available as an update for Eclipse Kepler (2013 Release) and is now available nightly / integration builds towards Eclipse Luna (2014 Release).
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
