Question

我正在尝试通过我的第一个JMOCK教程http://www.jmock.org/getting-started.html，并且进展不顺利。

我遇到的问题如下：


java.lang.SecurityException: class "org.hamcrest.TypeSafeMatcher"'s signer information does not match signer information of other classes in the same package

我在互联网上找到了解决方案。请参阅以下内容：

解决方案是确保发生对JMock JAR的任何依赖在每个插件中依赖于JUnit之前。那样，哈姆克雷斯特就是从JMock加载而不是从JUnit加载。

我对解决方案的理解是：让测试类使用JMock的hamcrest jar而不是Junit的jar？我对吗？我应该在Eclipse中做些什么来实现它？

谢谢，

Answer 1

Eclipse构建配置中的库顺序为：

hamcrest核-1.2.jar hamcrest库-1.2.jar JMock的-2.5.1.jar JRE [JavaSE-1.6] JUnit_4.8.1.jar（eclipse发行版的一部分） hamcrest.core_1.1.0（与JUnit 4.8.1捆绑在一起）

解决方案很简单 - 确保hamcrest.jar位于类路径中Eclipse包含的JUnit库之前。

我相信如果你看一下java build path属性（Configure Build Path）中的“Order and Export”选项卡，你会发现JUnit jar在hamcrest.jar之上。您可以在此处将Hamcrest移动到JUnit jar上方，问题就会消失。

Answer 2

您可以使用不包含hamcrest类型的junit- dep .jar（而不是junit.jar）。然后jmock中的hamcrest引用不会发生冲突。

Answer 4

由于项目中存在重复的JUnit依赖性，这发生在我身上。一个由eclipse添加，一个来自Maven依赖项（m2eclipse / m2e也将此类添加到类路径中）。

通过转到Project＆gt;删除eclipse添加的项目。属性＆gt;构建路径

见下文。 enter image description here

Answer 5

我遇到了同样的问题，试图在我刚刚导入的非Eclipse项目中运行测试。看完这里的其他答案后，我注意到pom.xml指定了JUnit 3 。

所以我只是改变了＃34; JUNIT_CONTAINER / 4＆＃34;到＆＃34; JUNIT_CONTAINER / 3＆＃34;在.classpath ...并且所有测试都成功了。
