GWTMockito：编写测试时出现java.lang.NoClassDefFoundError。 为什么？

Question

I'm attempting to write my first test for my GWT site but when I run my tests from the command line (I am developing with Eclipse though) I get the following error:

[junit] java.lang.NoClassDefFoundError: com/google/gwt/user/client/ui/Composite

I have included gwt-user.jar in my webapp/WEB-INF/lib folder too.

Anyone have any idea what is wrong??

原来我的测试编译类路径甚至都没有设置！
