How to use default and static methods on interfaces w Eclipse Kepler / JDK 8? [message #1265072]

In trying to do the examples at docs.oracle.com/javase/tutorial/java/IandI/defaultmethods.html, which "reflect features and conventions of the upcoming Java SE 8 release". The default methods and static methods per the code examples do not seem to be supported by the Eclipse Kepler compiler, even while I'm using the suggested "current JDK 8 snapshot from java.net.".

In particular, the following lines cause compiler errors:

    static ZoneId getZoneId (String zoneString) {...

--> error:
Quote:

Multiple markers at this line
- Abstract methods do not specify a body
- Illegal modifier for the interface method getZoneId; only public & abstract are permitted

Syntax error on token "default", delete this token

--> error:

Any ideas on how to get the default and static methods on the interface to compile?

No Java 8 feature can be supported by a released JDT compiler as long as Java 8 is not released.

See https://wiki.eclipse.org/JDT/Eclipse_Java_8_Support_%28BETA%29 for the latest bits (release candidate 2 as of yesterday).

As of May 9 2014 you can now fully use the Java 8 features just download 'Eclipse Java 8 Support' from eclipse marketplace.
