java - 使用 Leiningen 部署 Clojure 应用程序

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)

还有我的 core.clj 文件:

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

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

lein run -m raj.core 正常显示 Hello World 消息。所以接下来我尝试 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都很顺利，所以我尝试了 java -jar raj-0.0.1-SNAPSHOT-standalone.jar，我收到了

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

我会在这里做错什么？

您需要向raj.core 命名空间添加一个:gen-class 声明:

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