GRAILS: buildconfig.groovy and buildconfig.java

IDEA could not do it)))
What is the content of buildconfig.java?

IDEA - did it, I didn't type this code. These are the content of BuildConfig.java and BuildConfig.groovy has vanashied. Amazing.

        };

    }

    public BuildConfig(Binding binding) {
        super(binding);
    }

    public BuildConfig() {
        super();
    }
}

Anyone knows whats going on there?
