我正在尝试完成我的第一个 JMOCK 教程http://www.jmock.org/getting-started.html,但进展并不顺利。

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。请看下面:

解决方案是确保在每个插件中对 JMock JAR 的任何依赖都发生在对 JUnit 的依赖之前。这样,Hamcrest 是从 JMock 加载的,而不是从 JUnit 加载的。

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

谢谢,

Eclipse 构建配置中的库顺序为:

hamcrest-core-1.2.jar hamcrest-library-1.2.jar jmock-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 捆绑。 1)

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

相信如果您查看java构建路径属性(Configure Build Path)中的“Order and Export”选项卡,您会发现JUnit jar在hamcrest.jar之上。您可以在此处将 hamcrest 移到 JUnit jar 上方,问题就会消失。

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

由于项目中重复的 JUnit 依赖项,这发生在我身上。一个由 eclipse 添加,一个来自 Maven 依赖项(m2eclipse/m2e 也将这个添加到类路径中)。

因此,通过转到 Project > Properties > Build Path 来删除 eclipse 添加到项目中的那个

见下文。 在此处输入图像描述

我刚刚在我刚刚导入的非 Eclipse 项目中运行测试时遇到了同样的问题。在这里查看其他答案后,我注意到 pom.xml 指定了 JUnit 3

所以我只是在...中将“JUNIT_CONTAINER/4”更改为“JUNIT_CONTAINER/3” .classpath,所有测试都成功了。
