java - JUnit 插件测试忽略 Eclipse Neon 中的目标平台

Question

我在使用 Eclipse Neon M7 进行 JUnit 插件测试时遇到了一些问题，我真的很想听听任何使用测试的人的意见(必须有某人，对吧？) .

每当我开始一个在 Eclipse Luna 中工作的测试(但 didn't in Mars ，我认为它是一个错误)并继续使用 Tycho 工作时，我得到以下异常:

很明显，此时这不是 Eclipse 错误，但我做错了什么。没有迹象表明在测试中启动了什么样的插件，但从版本范围来看我认为它又是错误的 - 正在运行的 Eclipse 实例的插件而不是工作区目标中定义的插件平台。

启动配置仍然声称使用了较晚的目标平台。

如何配置插件单元测试以使其采用当前 Activity 的目标平台？

这里的问题是 Eclipse 4.4(Luna，2014)及更低版本的 org.eclipse.core.runtime 与 org.eclipse 的主机 Eclipse 版本兼容.pde.junit.runtime。当依赖性增加时，这种情况随着 4.5 发生了变化。

正如您正确地断定配置指向错误的org.eclipse.pde.junit.runtime。这可能是由于未清除的配置状态。确保清除配置，这样您就不会使用过时的版本运行。这是确保在启动配置的配置选项卡中选中启动前清除配置区域。

通过查看 ${workspace_loc}/.metadata/.plugins/org.eclipse.pde.core/pde-junit/org.eclipse.equinox，您可以准确地看到 PDE 将哪些解析为已配置的包。 simpleconfigurator/bundles.info(在启动配置的配置选项卡中指定的位置)
