Eclipse 如何正确地修补功能？（在没有插件的情况下安装功能补丁）

导言：我已经在P2论坛上问过这个问题，但我还没有得到任何答案，这个问题对我来说非常重要，因为它完全阻碍了我的工作

我需要修补当前的Mylyn-Context.Core功能，因此我检查了插件org.eclipse.Mylyn.Context.Core（3.6.1），创建了一个修复程序，并将版本更新为3.6.2。 之后，我创建了一个功能补丁项目，它在版本3.6.1.v20110728-0200中修补org.eclipse.mylyn.context_功能。 我将我的补丁插件添加到该功能的依赖项中

当我导出p2存储库（包括需要补丁的插件的特性）时，我得到了一个看起来正确的folderstructure。所有功能和插件都有正确的版本

当我安装补丁时，P2不会抱怨缺少需求，并且安装时没有错误

现在的问题是，在eclipse的plugins文件夹中，版本3.6.1中只有org.eclipse.mylyn.context.core。。。。但不是3.6.2，因此我的插件不工作。 奇怪的是，安装了补丁功能，但它没有抱怨缺少一个捆绑包（补丁的3.6.2）。

我将contents.xml与Oracle OEPE工具的补丁进行了比较，看起来一切都是正确的

有人能帮帮我吗。两个星期以来，我一直在努力解决这个问题，但没有取得任何进展

提前谢谢 马克

我从生成的P2存储库中添加了生成的content.xml
