Answer 1

Hey,

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.

First copy your workspace, then install another instance of eclipse. Try to open the workspace in that eclipse.

If that doesn't work, it seems a big problem. May be you need to import all projects again in new workspace.

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.

I hope, this works for you.

---EDIT on 21st May,2010---

After searching it ,it seems a bug in eclipse 3.4. Thought it shows a bug of WinXP, may be it affects MAC also.

Please check the link below. They have specified version 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.

Eclipse download: http://www.eclipse.org/downloads/

Bug: https://bugs.eclipse.org/bugs/show_bug.cgi?id=217707

Hope this helps.

thanks.

Answer 2

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?

Maybe it might throw some light on whats going wrong.

Answer 3

Well.. after updating my mac... everything is back to normal... !
