Super dev mode GWT with IntelliJ

Question

I had issues with GWT compiles. I am using GWT 2.7.0 and I use Java 8.

When I start dev-mod I get this exception :

java.lang.NoSuchFieldError: originalSourceLevel

I added <gwtSdkFirstInClasspath>true</gwtSdkFirstInClasspath> in my pom.xml and still the same problem. Any suggestion please?

I find using GWT 2.8.0-SNAPSHOT (nightly) works best with Java 1.8 app. That doesn't mean it won't work with 2.7, like the folks said above. Although I'm not worried about breaking changes either, as I think it's in the last stages of formulation before release.
