问题描述
我正在尝试创建一个插件来模拟Eclipse打开的资源对话框（CTRL + SHIFT + R）。我学习了如何创建一个FilteredItemsSelectionDialog，遵循。但是，缺少的是如何使用工作空间资源填充对话框。我发现，我试图在我的插件中复制这个功能，所以我可以逐步了解它的工作原理。所以我复制源并重命名它以避免与真实的冲突。问题是我不能导入这些类：
I'm trying to create a plug-in to mimic the Eclipse open resource dialog (CTRL+SHIFT+R). I've learned how to create a FilteredItemsSelectionDialog by following the example. But the missing piece is how to fill the dialog with the workspace resources. I found OpenResourceHandler and am trying to duplicate this functionality in my plug-in, so I can step through and see how it works. So I copy the source and rename it to avoid colliding with the real one. The problem is that I cannot import these classes:
import org.eclipse.core.resources.IContainer;
import org.eclipse.core.resources.IFile;
import org.eclipse.core.resources.IResource;
import org.eclipse.core.resources.ResourcesPlugin;
我尝试编辑我的清单，但它不会让我导入org.eclipse.core（虽然我可以import org.eclipse.core.runtime）。那么，我在哪里可以找到这些类，如何导入？而且，更重要的是，一般来说，我如何找到一个给定类的bundle并导入它？
I tried editing my Manifest but it will not let me import org.eclipse.core (although I can import org.eclipse.core.runtime). So, where do I find these classes and how can import them? And, more importantly, in general how would I find the bundle a given class exists in and import it?
推荐答案
你需要导入 org.eclipse.core.resources 。
一般来说，您可以打开插件视图（窗口 - >显示视图 - >其他 - >插件开发 - >插件）。然后，选择有趣的插件，然后右键单击 - >添加到Java搜索。然后，您可以使用打开类型（Ctrl + Shift + T）打开类。
In general, you can open the "Plug-ins" view (Window -> Show View -> Other -> Plug-in Development -> Plug-ins). Then, select interesting plug-ins and right click -> Add to Java Search. Then you can use Open Type (Ctrl + Shift + T) to open the class.
此外，在包资源管理器中，更改过滤器以不排除在图书馆工程。 链接到编辑器可以显示您刚才打开的课程包含什么。
Also, in the package explorer, change the Filters to not exclude "External plug-in libraries project". "Link with Editor" can then show you what bundle contains the class you just opened.
