Hack to get my afterEvaluation blocks to go before other ones.

build.gradle

beforeAfterEvaluate {
    println "Nah, nah, nah. I'm first"
}

util.gradle

def BroadcastDispatch<ProjectEvaluationListener> getProjectEvaluationListeners() {
    ProjectEvaluationListener listener = ((AbstractProject) project).getProjectEvaluationBroadcaster();
    def /* org.gradle.messaging.dispatch.ProxyDispatchAdapter.DispatchingInvocationHandler */ h = ((java.lang.reflect.Proxy) listener).h
    BroadcastDispatch<ProjectEvaluationListener> dispatcher = h.dispatch
    return dispatcher
}

def beforeAfterEvaluate(Closure beforeEvaluateClosure) {
    BroadcastDispatch<ProjectEvaluationListener> broadcast = getProjectEvaluationListeners()

    final String methodName = 'afterEvaluate'
    Dispatch<MethodInvocation> invocation =  new ClosureBackedMethodInvocationDispatch(methodName, beforeEvaluateClosure)

    Map<Object, Dispatch<MethodInvocation>> prependedHandlers = new LinkedHashMap<Object, Dispatch<MethodInvocation>>();
    prependedHandlers.put(invocation, invocation);
    prependedHandlers.putAll( broadcast.handlers )

    broadcast.handlers.clear()
    broadcast.handlers.putAll(prependedHandlers)   
}
