java - Eclipse 中的 Junit 测试失败，并出现 java.lang.NoClassDefFoundError : org/hamcrest/SelfDescribing

Question

我的测试运行良好，但后来我不得不重新安装 Eclipse。现在，即使是最简单的测试也会失败，并出现以下错误:

java.lang.NoClassDefFoundError: org/hamcrest/SelfDescription

我已尝试遵循回答类似问题的建议，但无法解决该错误。我已将 Junit 库添加到项目中，尝试将 junit-4.11.jar 和 junit-4.10.jar 添加到类路径中，并且尝试将 hamcrest-core-1.3.jar 添加到类路径中。

我在运行 OS 10.9、java 版本“1.6.0_65”的 Mac 上使用 Eclipse 4.3.2

这是来自 Eclipse 的跟踪:

有什么建议吗？

谢谢

尝试在类路径中添加 hamcrest-all-1.3.jar
