我正在尝试运行一个clojure jar文件,我收到以下错误:
C:\Users\Nahashon>java -jar C:\Users\Nahashon\.m2\repository\org\enclojure\sample\0.0.1\sample-0.0.1.jar
Exception in thread "main" java.lang.NoClassDefFoundError: com/mode/mdzw
Caused by: java.lang.ClassNotFoundException: com.mode.mdzw
at java.net.URLClassLoader$1.run(Unknown Source)
at java.security.AccessController.doPrivileged(Native Method)
at java.net.URLClassLoader.findClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source)
at java.lang.ClassLoader.loadClass(Unknown Source)
Could not find the main class: com.mode.mdzw. Program will exit.
使用maven on netbeans 6.9.1创建了clojure项目。而clojure代码如下:
(ns com.mode.mdzw
(:gen-class))
(defn -main []
(println "Looks like it works!"))
POM文件如下:

我做得不对?
答案 0 :(得分:1)
如果您刚入门,我建议您使用leiningen,此时您可以尝试Ankur's advice above或在project.clj中设置:main
。
(defproject org.enclojure/sample "0.1.0-SNAPSHOT"
:dependencies [[org.clojure/clojure "1.4.0"]]
:main com.mode.mdzw)
然后只需运行lein run
即可启动您的程序。如果你想要一个jar你可以执行w / o lein,用lein uberjar
构建它。
有关详情,请参阅leiningen tutorial。
如果你想坚持使用maven(我没有用太多),你应该查看clojure-maven-plugin的文档,它已经在你的pom中,但可能没有正确设置。它提供clojure:compile
目标,可能会满足您的需求。
我认为显而易见的问题是,在运行java -jar C:\Users\Nahashon\.m2\repository\org\enclojure\sample\0.0.1\sample-0.0.1.jar
之前,您的目标是什么?
