我有一个使用 Jetty WebSocket 客户端的 RCP 应用程序。我创建了一个插件，它包装了 jetty websocket 客户端代码以及其他 jetty 依赖项，并且可以正常工作。
现在我想在我的 RCP 目标中包含码头，而不是使用包装码头代码的插件。我向我的目标添加了一个指向码头更新站点的位置，选择所需的码头版本，并取消选中“包含所需软件”选项。目标似乎加载成功，但一些曾经出现在目标中的插件消失了。
例如，在添加码头位置之前，当我过滤 xtend 时，在内容选项卡上，我看到包 org.eclipse.xtend，它是从位置http://download.eclipse.org/releases/luna加载的。添加码头位置后，包 org.eclispe.xtend 不再出现在内容选项卡上。在添加码头位置之前和之后，在目标编辑器 UI 中，我为 luna 发布位置选择了各种功能，包括 EMF SDK、EMF Xcore SDK 和四个 Graphiti 功能。UI 中没有任何变化，所以我不明白为什么简单地添加一个指向码头更新站点的位置会使包在其他位置消失。
我尝试编辑目标源文件，只需添加码头位置并在文件顶部碰撞序列计数器，我得到相同的结果。我还尝试在 luna 发布位置明确添加 XTend 功能，但也无济于事。
这只是丢失的插件的一个示例。还有一些也消失了。似乎仅仅添加一个指向码头更新站点的位置就使我的目标无法使用。
任何人都可以分享如何将码头添加到 RCP 目标的任何示例吗？
