我有一个使用Jetty WebSocket客户端的RCP应用程序。我创建了一个插件来包装jetty websocket客户端代码，以及其他jetty依赖项，这样就可以了。
现在我想在我的RCP目标中包含jetty，而不是使用包装jetty代码的插件。我向目标添加一个指向jetty update site的位置，选择所需的码头版本，然后取消选中选项＆＃34;包含所需的软件＆＃34;。目标似乎成功加载，但是一些曾经出现在目标中的插件消失了。
例如，在添加jetty位置之前，当我过滤xtend时，在内容选项卡上，我看到了从位置http://download.eclipse.org/releases/luna加载的包org.eclipse.xtend。添加jetty位置后，内容选项卡上将不再显示包org.eclispe.xtend。在添加jetty位置之前和之后，在目标编辑器UI中，我为luna版本位置选择了各种功能，包括EMF SDK，EMF Xcore SDK和四个Graphiti功能。用户界面中没有任何内容发生变化，因此我不明白为什么只添加指向jetty更新站点的位置会使捆绑包在其他位置消失。
我尝试编辑目标源文件，只需添加jetty位置并在文件顶部碰撞序列计数器，我得到相同的结果。我也尝试在luna版本位置明确添加XTend功能，但也无济于事。
这只是一个缺失的插件的一个例子。还有一些也消失了。似乎添加指向jetty更新站点的位置这一事实使我的目标无法使用。
任何人都可以分享如何将jetty添加到RCP目标的任何示例吗？
编辑：添加指向jetty的位置之前和之后的目标文件
