lein appengine-подготовить не удается

Я пытаюсь заставить Clojure / Compojure/appengine-magic работать, следуя примеру в https://github.com/gcv/appengine-magic

Но когда я бегу lein appengine-prepare я получаю:

Exception in thread "main" C:UsershenrikIdeaProjectssimple-examplelibdev not found. (NO_SOURCE_FILE:0)

Я что-то пропустил?

lein new simple-example

Редактировать проект.clj:

(defproject simple-example "1.0.0-SNAPSHOT"
  :description "FIXME: write description"
  :dependencies [[org.clojure/clojure "1.2.1"] [appengine-magic "0.4.1"]])

lein deps

lein appengine-new

Редактировать ядро.clj:

(ns simple-example.core
  (:use compojure.core)
  (:require [appengine-magic.core :as ae]))

(defroutes simple-example-app-handler
  (GET "/" req
       {:status 200
