JUnit插件测试忽略Eclipse Neon中的目标平台 [英] JUnit Plug-in Test Ignores Target Platform in Eclipse Neon
问题描述
每当我开始在Eclipse Luna中工作的测试（但是没有在火星，我认为是一个错误），并继续使用Tycho我得到以下异常：

显然，这不是Eclipse的bug，但我做错了事情。在测试中没有指示什么样的插件启动，但从版本范围来看，我认为它是错误的 - 运行的Eclipse实例的插件，而不是在工作区的目标中定义的插件平台。
仍然是发布配置声称使用的是以后的目标平台。
如何配置插件单元测试，以便它将占用当前活动的目标平台？
这里的问题是Eclipse 4.4（Luna，2014）及以下版本具有兼容主机Eclipse的 org.eclipse.core.runtime org.eclipse.pde.junit.runtime 的版本。当依赖关系增加时，该值随4.5变化。
正如您正确地得出结论，配置指向错误的 org.eclipse.pde.junit.runtime 的。这可能是由于未清除配置状态。确保配置正在被清除，因此您不会以陈旧的版本运行。这确保在启动配置的配置选项卡中选中清除配置区域。
您通过查看 $ {workspace_loc} /。metadata / .plugins / org.eclipse.pde.core / pde-junit / org.eclipse.equinox.simpleconfigurator / bundles，可以准确了解PDE解析为配置的捆绑包。信息（在启动配置的配置选项卡中指定的位置）
I have some problems getting JUnit plug-in tests to work using Eclipse Neon M7 and I'd really like input from anybody out there who uses tests (there has to be somebody, right?).
Whenever I start a test that works in Eclipse Luna (but didn't in Mars, which I assumed was a bug) and continues to work using Tycho I get the following exception:

Clearly it's not a Eclipse bug at this point, but I'm doing something wrong. There is no indication what kind of plug-ins are started in the test, but judging from the version ranges I assume it's the wrong ones again - the plug-ins of the running Eclipse instance instead of the plug-ins defined in the workspace's target platform.
Still the launch configuration claims the later target platform is used.
How do I configure a plug-in unit test so that it will take the currently active target platform?
The problem here is that Eclipse 4.4 (Luna, 2014) and below had a version of org.eclipse.core.runtime that was compatible with the host Eclipse version of org.eclipse.pde.junit.runtime. That changed with 4.5 when the dependency increased.
As you have correctly concluded that the configuration is pointing at the wrong org.eclipse.pde.junit.runtime. This is probably due to uncleared configuration state. Ensure that the configuration is being cleared, so you don't run with a stale version. That is ensure that Clear the configuration area before launching is checked in the Configuration tab of launch configuration.
You can see exactly what PDE has resolved as the configured bundles by looking at ${workspace_loc}/.metadata/.plugins/org.eclipse.pde.core/pde-junit/org.eclipse.equinox.simpleconfigurator/bundles.info (location specified in Configuration tab of launch configuration)
