Ratpack and runtime class reloading

Ratpack works very smoothly with spring-loaded library. It is defined as dependency in build.gradle file. Spring-loaded enables runtime hot class reloading.

dependencies {
    springloaded "org.springframework:springloaded:1.2.0.RELEASE"
}

But default configuration reloads only changes in Ratpack.groovy file.
