我如何获得'cake repl'在OSX上的工作？ （我得到'线程中的异常'主要“java.lang.NoClassDefFoundError：clojure/main'）

Question

我试图让clojure/emacs/swank/cake一起工作。根据assembla我需要'蛋糕repl'来启动一个repl，但我不断收到NoClassDefFoundError。任何想法如何解决这个问题？

这就是我在命令行中得到：

$ cake ps 
7876 main -Dcake.project=/Users/bmaddy/.cake -Xms16M -Xmx64M -Djava.library.path=lib/dev/native 
$ echo $CLASSPATH

Answer 1

原来这是Clojure和Java 1.5的问题。 OS X的修正是使用/Applications/Utilities/Java Preferences.app切换到Java 1.6。

Answer 2

貌似默认蛋糕项目没有Clojure的罐子。尝试运行cake deps force。
