在Eclipse Indigo中运行JUnit插件测试的正确目标平台？ [英] Right target platform for running JUnit plugin tests in Eclipse Indigo?

问题描述

对于我的Eclipse插件项目，我定义了以下目标平台：

For my Eclipse plugin project, I have defined the following target platform:

<location includeAllPlatforms="true" includeMode="slicer" includeSource="true" type="InstallableUnit">
  <unit id="org.eclipse.equinox.executable.feature.group" version="3.5.0.v20110530-7P7NFUFFLWUl76mart"/>
  <unit id="org.eclipse.rcp.sdk.id" version="3.7.1.M20110909-1335"/>
  <unit id="org.eclipse.jdt.feature.group" version="3.7.1.r371_v20110810-0800-7z8gFcoFMLfTabvKsR5Qm9rBGEBK"/>
  <unit id="epp.package.java" version="1.4.1.20110909-1818"/>
...

我的插件具有JUnit插件测试（在同一个插件中）。如果我尝试使用JUnit启动配置（ org.eclipse.platform.ide ）运行它们，我将收到以下关于 junit 和一个例外：

My plugin has JUnit plugin tests (in the same plugin). If I try to run them with a JUnit launch config (org.eclipse.platform.ide), I get the following console messages about junit, and an exception:

使用默认的JDT安装，单元测试运行正常，只是我想要为Hudson-build定义一个合适的目标平台。不用说，我尝试在各个地方的两个违规平台上添加依赖关系，无济于事。

With the default JDT installation, the unit test runs fine, it's just that I want to define a proper target platform for a Hudson-build. Needless to say, I tried adding dependencies on the two offending platforms in various places, to no avail.

更新：
Whoops我混淆了另一套测试;这些不是无头，而是工作台测试。

Update: Whoops, I confused this with another set of tests; these here are not headless but workbench-tests.

另一个奇怪的是，有时我在切换到默认值后首次运行测试时不会看到此错误Eclipse平台回我的。

Another oddity is that sometimes I won't see this error when running the test for the first time after switching to the default Eclipse platform and back to mine. Odd.

推荐答案

我不喜欢在这里吹我自己的角，但现在我可以想到的唯一的解决方法在另外几个小时的实验之后）将launch-config设置为所有工作区和启用的目标插件，而不是使用功能或基于插件的启动。我认为这表明在插件解析过程中，Eclipse默认情况下是正确的，但是当您开始限制可用的功能/插件时，并不是这样。

I don't like to blow my own horn here, but the only workaround I could come up with now (after another few hours of experimentation) is setting the launch-config to "all workspace and enabled target plugins" instead of either using a feature or plugin-based launch. I think this indicates that there is something fishy in the plugin-resolution process which Eclipse gets right by default, but not when you start restricting the available features/plugins.

这种变化似乎可以在Eclipse和Buckminster中可靠地工作（从原始问题的问题设置中离开目标平台（！））。所以我得出结论，目标平台原则上是正确的，它一定是关于发布的一些东西。

With that change, it seems to reliably work both within Eclipse and Buckminster (leaving the target platform unchanged(!) from the problematic setup in the original question). So I conclude that the target platform is in principle correct, it must have been something about the launch.
