I've installed JDK 8. I set my JAVA_HOME to the JDK 8 directory. I downloaded the latest Eclipse Luna. I checked for updates. I set my default (and only) Installed JRE to the JDK 8 directory.

I cannot set my project nor workspace compliance level to 1.8. I even tried manually editing the preferences file to 1.8 to no avail.

What am I doing wrong? Hopefully it's something simple.

PS My project builds with java 8 fine. I'm using gradle with source and target set to 1.8 and it builds and generates eclipse files, but still doesn't work.

Luna will support Java 8 by default starting at Luna M7. For the time being you can install the Java 8 support patch for Kepler (either on Luna or Kepler).

Here is the update site: http://download.eclipse.org/eclipse/updates/4.3-P-builds/

The link is a 404 now.
Java 8 is now available in Eclipse Luna: eclipse.org/downloads/index-developer.php . For Kepler just look for Java8 in eclipse marketplace client or download java 8 capable edition of kepler: eclipse.org/downloads/index-java8.php
