easymock - easymock 依赖于 net/sf/cglib/proxy/Enhancer 吗？

Question

我正在尝试完成有关 easymock 的教程以首次使用它。 http://www.vogella.de/articles/EasyMock/article.html

我正在使用- 面向 Java 开发人员的 Eclipse IDE(内部版本号:20100218-1602)
- Junit 4插件
- Easymock 3.0

按照如下所述创建项目并作为 JUNIT 测试执行后，我收到错误。

**java.lang.NoClassDefFoundError: net/sf/cglib/proxy/Enhancer**            

这个错误是什么以及如何修复它？它发生在线路上

EasyMock.replay(calcMethod);

是的，我想你需要它。

http://cglib.sourceforge.net/

它也可能位于 Easymock 下载中的某种依赖项目录中
