使用Leiningen部署Clojure应用

Question

到目前为止，这是我的project.clj文件：

(defproject raj "0.0.1-SNAPSHOT"
  :description "FIXME: write description"
  :dependencies [[org.clojure/clojure "1.3.0"]]
  :keep-non-project-classes true
  :main raj.core)

和我的core.clj文件：

(ns raj.core
  (:use raj.core))

(defn -main [& args]
  (println "Hello World!!!"))

lein run -m raj.core显示Hello World消息就好了。所以下次我尝试lein uberjar并获得

Compiling raj.core
Compilation succeeded.
Created C:\Users\bobjones\IdeaProjects\raj/raj-0.0.1-SNAPSHOT.jar
Including raj-0.0.1-SNAPSHOT.jar
Including clojure-1.3.0.jar
Created C:\Users\bobjones\IdeaProjects\raj/raj-0.0.1-SNAPSHOT-standalone.jar

到目前为止，一切似乎进展顺利，所以我尝试了java -jar raj-0.0.1-SNAPSHOT-standalone.jar，然后我收到了

Error: Could not find or load main class raj.core

我在这里怎么做错了？

Answer 1

您需要向名称空间添加:gen-class声明raj.core：

(ns raj.core
  (:use raj.core)
  (:gen-class))
