importing org.eclipse.core packages for Eclipse plug-in
提问by harschware
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 OpenResourceHandlerand 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:
我正在尝试创建一个插件来模拟 Eclipse 打开资源对话框 (CTRL+SHIFT+R)。我已经按照示例学习了如何创建 FilteredItemsSelectionDialog 。但缺少的部分是如何用工作区资源填充对话框。我找到了OpenResourceHandler并试图在我的插件中复制这个功能，这样我就可以逐步了解它是如何工作的。所以我复制源并重命名它以避免与真实的冲突。问题是我无法导入这些类：
import org.eclipse.core.resources.IContainer;
import org.eclipse.core.resources.IFile;
import org.eclipse.core.resources.IResource;
import org.eclipse.core.resources.ResourcesPlugin;
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?
我尝试编辑我的清单，但它不会让我导入 org.eclipse.core（虽然我可以导入 org.eclipse.core.runtime）。那么，我在哪里可以找到这些类以及如何导入它们？而且，更重要的是，通常我如何找到给定类存在的包并导入它？

You need to import org.eclipse.core.resources.
您需要导入org.eclipse.core.resources.
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.
一般情况下，可以打开“插件”视图（Window -> Show View -> Other -> Plug-in Development -> Plug-ins）。然后，选择有趣的插件并右键单击 -> 添加到 Java 搜索。然后您可以使用 Open Type (Ctrl + Shift + T) 打开类。
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.
此外，在包资源管理器中，将过滤器更改为不排除“外部插件库项目”。“Link with Editor”然后可以显示包含您刚刚打开的类的包。
