解决“java.lang.NoSuchMethodError: org.hamcrest.core.AllOf.allOf…”问题（使用JUnit和Hamcrest）

解决“java.lang.NoSuchMethodError: org.hamcrest.core.AllOf.allOf…”问题（使用JUnit和Hamcrest）

 

junit-4.10.zip（下载地址：http://sourceforge.net/projects/junit/files/junit/4.10/）

hamcrest-1.3.zip（下载地址：http://code.google.com/p/hamcrest/downloads/list）

 

        将junit-4.10.jar、hamcrest-core-1.3.jar和hamcrest-library-1.3.jar导入到工程中，出现如下错误：

解决办法：

        在Eclipse中，“Java BuildPath”->“Order and Export”将hamcrest有关的jar包，排在junit包的前面，如下
