Eclipse 不会在包资源管理器中显示文件

Eclipse won't show files in package explorer

提问by Colleen

I don't know what went wrong, because this was working before, but all of the sudden I don't have any files in my eclipse package explorer.

我不知道出了什么问题，因为这以前是有效的，但是突然之间我的 eclipse 包资源管理器中没有任何文件。

The workspace path appears to be correct and the file permissions are correct.

工作区路径似乎正确且文件权限正确。

Can anyone think of what's wrong?

任何人都可以想到什么是错的？

I had the same problem (Probably caused when I cancelled a copying to my Dropbox folder) I only needed to click File → Import → General → Existing Projects into Workspaceand select the missing projects in the window that appeared.

我遇到了同样的问题（可能是因为我取消了对 Dropbox 文件夹的复制）我只需要File → Import → General → Existing Projects into Workspace在出现的窗口中单击并选择丢失的项目。

• Refresh the project
• If that does not work, close and open the project again.

• 刷新项目
• 如果这不起作用，请关闭并再次打开该项目。

Don't know what causes the problem, but found a way to get the files back into the package explorer.

不知道是什么原因导致了问题，但找到了一种方法将文件放回包资源管理器中。

If you go into the path of your workspace and find your projects, then you can pack them all into a zip archive file, and from this zip archive file you can import your projects again by using the File → Import → General → Existing Projects into Workspacemenu.

如果您进入工作区的路径并找到您的项目，那么您可以将它们全部打包到一个 zip 存档文件中，然后您可以从该 zip 存档文件中再次使用File → Import → General → Existing Projects into Workspace菜单导入您的项目。

I don't know what causes the problem, but in my case I think it have something to do with me having my workspace in a dropbox folder.

我不知道是什么导致了这个问题，但就我而言，我认为这与我将工作区放在 Dropbox 文件夹中有关。

ps. I don't know if you actually can take more than one project into one zip file and make it work, I have only tried it with one project pr. ZIP-file, but it shouldn't matter.

附：我不知道你是否真的可以将多个项目合并到一个 zip 文件中并使其工作，我只尝试过一个项目公关。ZIP 文件，但应该没有关系。

I had started the wrong installation of eclipse. When I started the correct installation my code showed up fine. I have both C++ and Java EE installs.

我开始错误地安装了 eclipse。当我开始正确安装时，我的代码显示正常。我同时安装了 C++ 和 Java EE。

Just refresh all the projects, you able to see all missed files after you import from a workspace.

只需刷新所有项目，您就可以在从工作区导入后看到所有丢失的文件。

1) Make sure that you use the right workspace.

1) 确保您使用正确的工作区。

2) Choose your "workspace"-Folder "/YourWorkspace", NOTyour project folder"/YourWorkspace/yourProject"

2）选择您的“工作区”-文件夹“/YourWorkspace ”，而 不是您的项目文件夹“/YourWorkspace/yourProject”

Alternatively delete your project from your "YourWorkspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.location"

或者从“YourWorkspace>/.metadata/.plugins/org.eclipse.core.resources/.projects/PROJECTNAME/.location”中删除您的项目

and restart.

并重新启动。

Hope this helps
