junit.jar: Includes the Hamcrest classes. The simple all-in-one solution to get started quickly.Starting with version 4.11, Hamcrest is no longer included in this jar.junit-dep.jar: Only includes the JUnit classes but not Hamcrest. Lets you use a different Hamcrest version.注意黑色加下划线的部分。说明4.1.1中没有hamcrest包了，不知道作者是怎么想的。
最好的解决方法是：
(1)换成junit-4.8.jar
（2）junit-4.11.jar + hamcrest-core-1.3.jar
JUnit-4.11使用报java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing错误
