Version|Version 1.8 of project facet java does not exist. Version1.8ofprojectfacetjavadoesnote

I'm trying to build a Dynamic Web Application in eclipse using Java 8 (and Wildfly appServer if that matters) but I'm unable to make Eclipse Luna M5 use Java 8 (I do have Java 8 BETA support installed and it works on JavaSE projects).
In my POM I set the level to Java 8:

【Version|Version 1.8 of project facet java does not exist.】maven-compiler-plugin 3.1 1.8 1.8

But after I do maven -> update project I get the following error:

Could not update project ExampleApp configuration Version 1.8 of project facet java does not exist.

And indeed there is no java 1.8 project facet under project->preferences->project facets->java
Can I manually create such facet and add It to to eclipse or I'll have to wait until java 8 is released and the eclipse guys decide to add it ?

There are additional patches available for Kepler SR2 officially.In ecliplse, go to "Help" --> "Market Place" --> Search for java 8 kepler.Then choose and install the following.

install Java 8 support eclipse kepler sr2,
Java 8 Facets for web tools eclipse kepler sr2
Java 8 support for m2e for Eclipse Kepler SR2 (if required)

Reference: http://www.eclipse.org/downloads/java8/
After this, my multi-module maven project with java 8 is building fine without any error in eclipse kepler SR2.
UPDATE: If you are using Spring Tool Suite (STS), then version 3.5.1 has included these features.
