我应该运行哪个目录 java -jar my-webapp-0.1.0-standalone.jar

Question

在本教程中，它说

现在创建一个 uberjar 的 webapp （ via lein uberjar ），复制它 （ target/my-webapp-0.1.0-standalone.jar ） 到任何你喜欢的地方，以及 以通常的方式运行它：

java -jar my-webapp-0.1.0-standalone.jar 8080

我从它自己的目录运行它~/myapp/target/但出现错误：

Target $ Java -jar my-webapp-0.1.0-standalone.jar

在 my-webapp-0.1.0-standalone 中没有主清单属性.jar

-main函数已经在handler.clj中：

(ns my-webapp.handler
  (:require [my-webapp.views :as views]
            [compojure.core :as cc]
            [compojure.handler :as handler]
            [compojure.route :as route]
            [ring.adapter.jetty :as jetty]
            (:gen-class)))
(cc/defroutes app-routes
  (cc/GET "/"
       []
       (views/home-page))
  (cc/GET "/add-location"
       []
       (views/add-location-page))
  (cc/POST "/add-location"
        {params :params}
        (views/add-location-results-page params))
  (cc/GET "/location/:loc-id"
       [loc-id]
       (views/location-page loc-id))
  (cc/GET "/all-locations"
       []
       (views/all-locations-page))
  (route/resources "/")
  (route/not-found "Not Found"))
(def app
  (handler/site app-routes))
(defn -main
  [& [port]]
  (let [port (Integer. (or port
                           (System/getenv "PORT")
                           5000))]
    (jetty/run-jetty #'app {:port  port
                            :join? false})))

我做错了什么？

编辑

我正在添加我的project.clj：

(defproject my-webapp "0.1.0"
  :description "FIXME: write description"
  :url "http://example.com/FIXME"
  :dependencies [[org.clojure/clojure "1.5.1"]
                 [hiccup "1.0.2"]
                 [org.clojure/java.jdbc "0.2.3"]
                 [com.h2database/h2 "1.3.170"]
                 [compojure "1.1.6"]
                 [ring/ring-jetty-adapter "1.2.1"]]
  :main my-webapp.handler
  :plugins [[lein-ring "0.8.8"]]
  :ring {:handler my-webapp.handler/app}
  :profiles
  {:dev {:dependencies [[javax.servlet/servlet-api "2.5"]
                        [ring-mock "0.1.5"]
                        [org.clojure/java.jdbc "0.0.4"] ]}})

和handler.clj

    (ns my-webapp.handler
  (:require [my-webapp.views :as views]
            [compojure.core :as cc]
            [compojure.handler :as handler]
            [compojure.route :as route]
            [ring.adapter.jetty :as jetty])
  (:gen-class))
(cc/defroutes app-routes
  (cc/GET "/"
       []
       (views/home-page))
  (cc/GET "/add-location"
       []
       (views/add-location-page))
  (cc/POST "/add-location"
        {params :params}
        (views/add-location-results-page params))
  (cc/GET "/location/:loc-id"
       [loc-id]
       (views/location-page loc-id))
  (cc/GET "/all-locations"
       []
       (views/all-locations-page))
  (route/resources "/")
  (route/not-found "Not Found"))
(def app
  (handler/site app-routes))
(defn -main
  [& [port]]
  (let [port (Integer. (or port
                           (System/getenv "PORT")
                           5000))]
    (jetty/run-jetty #'app {:port  port
                            :join? false})))

您是否在部署 Web 应用部分中执行了此步骤

• 并添加：main my-webapp.handler

如果这没有帮助，那么您能否发布整个 project.clj 文件，以便我们查找其他问题？
