Eclipse sometimes behaves in weird manner. All all your source code folders ok? Please check all folder first. If they are ok then there must be something with the core plugins OR the workspace in which you have all your projects.
Eclipse 有时会以奇怪的方式运行。你所有的源代码文件夹都好吗？请先检查所有文件夹。如果它们没问题，那么核心插件或您拥有所有项目的工作区必须有一些东西。
First copy your workspace, then install another instance of eclipse. Try to open the workspace in that eclipse.
首先复制您的工作区，然后安装另一个 eclipse 实例。尝试在该日食中打开工作区。
If that doesn't work, it seems a big problem. May be you need to import all projects again in new workspace.
如果这不起作用，这似乎是一个大问题。可能您需要在新工作区中再次导入所有项目。
For better performance, you should keep number of projects in workspace somewhat limited. It seems you have many projects inside one workspace which might cause memory problems and slower your eclipse.
为了获得更好的性能，您应该限制工作区中的项目数量。似乎您在一个工作区中有许多项目，这可能会导致内存问题并减慢您的日食。
I hope, this works for you.
我希望，这对你有用。

After searching it ,it seems a bug in eclipse 3.4. Thought it shows a bug of WinXP, may be it affects MAC also.
搜索后，似乎是eclipse 3.4中的一个错误。以为是WinXP的bug，可能是MAC也有影响。
Please check the link below. They have specified version 3.4 M6.
请检查下面的链接。他们指定了版本 3.4 M6。
So if you are using older version of eclipse then please get newer from this link. Also please check to have JDK 1.6 (Stable version) installed on your mac.
因此，如果您使用的是旧版本的 eclipse，那么请从此链接获取更新版本。另外请检查您的 Mac 上是否安装了 JDK 1.6（稳定版）。

Can you check the Console (Applications -> Utilities -> Console.app) and see whether there are any specific messages from eclipse (and post them here if possible)? A exception stack trace or something?
您能否检查控制台（应用程序-> 实用程序-> Console.app）并查看是否有来自 eclipse 的任何特定消息（如果可能，请将它们张贴在这里）？异常堆栈跟踪什么的？
Maybe it might throw some light on whats going wrong.
也许它可能会为出了什么问题提供一些线索。
