Junit：创建BOFactory实例时出现exception

我正在尝试在IID8.5上设置JUnit框架。 但是当我尝试运行简单的JUnit测试用例时，我收到运行时错误。 （ java.lang.NoClassDefFoundError：org.eclipse.core.runtime.RegistryFactory ）

我正在使用JUnit4。 请查看显示项目结构的附图

该exception告诉您某个类不可用于您在其中运行的JVM。

简单的答案：然后开始搜索该类……你可以在这里找到它 – 你可以在这里下载各种与eclipse相关的JAR。

因此：尝试将org-eclipse-equinox-registry.jar添加到类路径中会发生什么。

（ 这里可能包含对正在发生的事情的解释）
