The example for the Gradle resolver in the README shows the following call:

Gradle.resolver()

But org.jboss.shrinkwrap.resolver.impl.gradle.Gradle is an internal implementation class, not API (https://github.com/shrinkwrap/resolver/blob/master/gradle/impl-gradle/src/main/java/org/jboss/shrinkwrap/resolver/impl/gradle/Gradle.java), so it's not visible.

Is the example wrong or should the class be moved to the API?

(BTW, the affected version field doesn't have 3.3.0)
