NoClassDefFoundError从Java（Android，LibGDX）调用Clojure

我随后使用Leiningen从Eclipse中的Java调用Clojure。我想在Clojure中编写游戏的AI，其余的则在Android操作系统的LibGDX中编写

完成Clojure端后，我使用lein命令将其打包到jar文件中（#lein compile，#lein run，#lein uberjar）

我右键单击项目>属性>Java构建路径>库>添加外部jar…>myai-0.1.0-SNAPSHOT-standalone.jar

我的问题发生在我执行游戏时

import myai.*;
public class Stack extends Actor {
   ...
   public void draw(SpriteBatch batch, float parentAlpha) {
      System.out.println("Binomial = " + core.binomial(5, 15));
   }
   ...
}

我收到这个错误：

12-26 00:27:01.570: I/dalvikvm(8384): Could not find method myai.core.binomial, referenced from method my.package.Stack.draw

我真的不知道为什么会这样，因为我已经遵循了教程中的所有步骤

这些是我的clojure文件：

project.clj

core.clj

提前感谢！：）

编辑：在Ubuntu中使用命令行命令也不起作用。

多么愚蠢的错误。。。我忘记在Properties>JavaBuildPath>Order and Export选项卡中检查Clojure.jar文件，因此在编译时它没有添加到类路径中
