如何修补功能？ （特征的补丁被无插件安装）

Question

介绍：我问在P2-论坛这个问题了，不过我不能得到任何答案了这个问题是非常重要的，我的，因为它完全挡住了我的工作

我需要修补当前的Mylyn-Context.Core功能，所以我检出了插件org.eclipse.mylyn.context.core（3.6.1），创建了一个修复程序并将版本更新到3.6.2 。 之后，我创建了一个功能修补程序项目，它修补了版本3.6.1.v20110728-0200中的org.eclipse.mylyn.context_feature。 我将修补后的插件添加到该功能的依赖关系中。

当我导出一个p2-repository（包含需要修补程序的插件的功能）时，我得到一个看起来正确的文件夹结构。所有功能和插件都有正确的版本。

当我安装补丁程序时，P2不会抱怨缺少需求并安装而没有错误。

现在的问题是，在eclipse的plugins文件夹中只有org.eclipse.mylyn.context.core在版本3.6.1 ....但不是3.6.2，因此我的插件没有工作。 奇怪的是，补丁功能已安装，但它并没有抱怨丢失的包（补丁3.6.2）。

我将contents.xml与来自Oracle OEPE Tools的补丁进行了比较，它看起来像一切都是正确的。

有人可以帮我在这里。我试图解决这个问题，因为两个星期没有再进一步。

在此先感谢 马克

附：我加了从生成P2-库

从bugzilla发现了同样的问题所产生的content.xml。

总而言之，您尝试修补不包括插件的功能。你应该修补“org.eclipse.mylyn_feature”。
