How would I get lein uberjar to return a jar that has the manifest file?

handler.clj

(ns skateproj.handler
  (:use compojure.core
        sandbar.stateful-session)
  (:require [clojure.string :as str]
            [skateproj.db :as db]
            [compojure.handler :as handler]
            [compojure.route :as route]
            [skateproj.routes :as r]
            [ring.adapter.jetty :refer [run-jetty]])
  :gen-class)

(defroutes app-routes
  ;; ..
)

(defn re-check [s rgx]
  (not (empty? (re-find rgx s))))

(defn add-trailing-slash
  "If the requested url has no trailing slash, add it."
  [handler]
  (fn [request]
    (if (.endsWith (:uri request) "/")
      (handler request)
      (let [newurl (str/replace (:uri request) #"(?<=.)$" "/")]
        {:status 301 :headers {"Location" newurl}}))))

(def app (-> app-routes
             handler/site
             add-trailing-slash
             wrap-stateful-session))

(defn start-server [port]
  (run-jetty app {:port port}))

(defn -main [& args]
  (let [port (Integer. (or (first args) "5000"))]
    (start-server port)))

output
