不能使用Leiningen构建一个jar [英] Can't build a jar using Leiningen

问题描述

我想使用Intellij的Cursive中的Leiningen插件从我的裸机Clojure项目中创建一个独立的jar。

要创建项目创建了project.clj文件，打开它，Cursive提供将其作为项目导入。

project.clj：

 （defproject WaterTimer1
：description提醒你喝水的计时器
：主音制作者/ b  

tone-producer.clj：

 （ns tone-producer 
（：require [general-helpers：as g]）
 
（：import [javax.sound.midi MidiSystem 
 Synthesizer 
 MidiChannel]）
（：gen-class））
 
（defn main [& args] 
（printlnTest！ 
 
 
 
当我运行uberjar任务时，我得到以下输出：
 
 
警告：指定：main不包含在：aot中。 
隐式AOT：main将在Leiningen 3.0.0中删除。 
如果你只需要AOT你的uberjar，考虑添加：aot：all到你的
：uberjar配置文件。 
警告：指定的Main-Class在jar中不存在。它可能无法按预期执行。 gen-class伪指令可能在包含main方法的命名空间中丢失。 
创建的C：\Users\slomi\IdeaProjects\WaterTimer\target\WaterTimer-1.jar 
创建的C：\Users\slomi\IdeaProjects\WaterTimer\ target\WaterTimer-1-standalone.jar 
 
 
我也尝试过更改主函数具有默认名称，并从 defproject 中省略名称：
 （defproject WaterTimer1
：description提醒你喝水的计时器
：主音制作者）
 
 b $ b（：require [general-helpers：as g]）
 
（：import [javax.sound.midi MidiSystem 
合成器
 MidiChannel]）
 ：gen-class））
 
（defn -main [& args] 
（printlnTest！））
  
但现在我遇到错误：
 
 
错误：找不到或加载主类clojure.main 
编译失败：子过程失败
 
 
结构是：
 
 
 
 
 
 WaterTimer 
 
 
 
 
 src 
 
 
 
 
 tone-producer.clj 
 
 
 
 
 
 project.clj 
 
 
目标
 
 
 
 
 
 
 
 
此处的任何指导都不胜感激。
  
 
 
 
 
 
我放了 
 
 
错误：无法找到或加载主类clojure.main编译失败
 
 
 
 
您未包含clojure依赖项[1] 
 
 
 
 
 
 ：gen-class 需要AOT-正如Sanchayan指出的
 
 
 
 
 
 
 
 
 
 
 
 
 project.clj 
 （defproject WaterTimer0.0.1
：description提醒你喝水的计时器
：dependencies [[org.clojure / clojure1.8.0 ]] ;; <  -  [1] 
：main tone-producer 
：aot [tone-producer]）;; <  -  [2] 
  
 src / tone_producer.clj  -   USE'_' ' - 'in the filename  
 （ns tone-producer 
（：import [javax.sound .midi MidiSystem 
 Synthesizer 
 MidiChannel]）
（：gen-class））
 
（defn -main [& args] 
（println Test！））
  
结果：
  $ lein uberjar 
编译音调生成器
编译音调生成器
创建... / watertimer / target / WaterTimer-0.0.1.jar 
 Created ... / watertimer / target / WaterTimer-0.0.1-standalone.jar 
 $ java -jar target / WaterTimer-0.0.1-standalone.jar 
 Test！ 
  
 
 
 
 
 
 
  lein new< name> 并将其导入Cursive /其他IDE选择。 
 
I'm trying to make a stand alone jar from my bare-bones Clojure project using the Leiningen plugin in Intellij's Cursive.

To create the project, I just created the project.clj file, opened it, and Cursive offered to import it as a project.

project.clj:
(defproject WaterTimer "1"
  :description "A timer that reminds you to drink water"
  :main tone-producer/main)
tone-producer.clj:
(ns tone-producer
  (:require [general-helpers :as g])

  (:import [javax.sound.midi MidiSystem
                             Synthesizer
                             MidiChannel])
  (:gen-class))

(defn main [& args]
  (println "Test!"))
When I run the "uberjar" task, I get the following output:

  
Warning: specified :main without including it in :aot. 
  Implicit AOT of :main will be removed in Leiningen 3.0.0. 
  If you only need AOT for your uberjar, consider adding :aot :all into your
  :uberjar profile instead.
  Warning: The Main-Class specified does not exist within the jar. It may not be executable as expected. A gen-class directive may be missing in the namespace which contains the main method.
  Created C:\Users\slomi\IdeaProjects\WaterTimer\target\WaterTimer-1.jar
  Created C:\Users\slomi\IdeaProjects\WaterTimer\target\WaterTimer-1-standalone.jar
I also tried changing the main function to have the default name, and omit the name from the defproject:
(defproject WaterTimer "1"
  :description "A timer that reminds you to drink water"
  :main tone-producer)

(ns tone-producer
      (:require [general-helpers :as g])

      (:import [javax.sound.midi MidiSystem
                                 Synthesizer
                                 MidiChannel])
      (:gen-class))

    (defn -main [& args]
      (println "Test!"))
But now I get the error:

  
Error: Could not find or load main class clojure.main
  Compilation failed: Subprocess failed
The structure is:


WaterTimer


src


tone-producer.clj

project.clj
target



Any guidance here would be appreciated.
解决方案
After a bit of fiddling


I dropped (:require [general-helpers :as g]) since its not necessary to demostrate the issue
Error: Could not find or load main class clojure.main Compilation failed


you didn't include the clojure dependency [1]

:gen-class needs AOT - as Sanchayan pointed out


see [2]



project.clj 
(defproject WaterTimer "0.0.1"
  :description "A timer that reminds you to drink water"
  :dependencies [[org.clojure/clojure "1.8.0"]] ;; <- [1]
  :main tone-producer    
  :aot [tone-producer])  ;; <- [2]
src/tone_producer.clj - USE '_' instead of '-' in the filename 
(ns tone-producer
  (:import [javax.sound.midi MidiSystem
                             Synthesizer
                             MidiChannel])
  (:gen-class))

(defn -main [& args]
  (println "Test!"))
Result:
$ lein uberjar
Compiling tone-producer
Compiling tone-producer
Created .../watertimer/target/WaterTimer-0.0.1.jar
Created .../watertimer/target/WaterTimer-0.0.1-standalone.jar
$ java -jar target/WaterTimer-0.0.1-standalone.jar 
Test!




Generally I'd recommend to init a project with lein new <name> via command line and the import it into Cursive/Other IDE of choice.
