Can I close Eclipse with all my projects when I exit?

Question

I would like to have Eclipse (3.5, if that matters) to close any open projects that I have before leaving the workspace. Is it possible?

EDIT I forgot to mention that these projects are stored remotely, and it would be nice for that reason.

Answer 1

^{Update 2011:}

To actually close all projects upon exit, you need a plugin similar to the one mentioned in this thread :

I implemented shutdown() my plugin to close the whole project and save the workspace.

Note: today you would use the stop() method for AbstractUIPlugin since shutdown() deprecated in Eclipse3.0 +.
In it you call IProject.close() .

But you also need to set the org.eclipse.ui.IWorkbenchPreferenceConstants.CLOSE_EDITORS_ON_EXIT parameter (the one I originally mentioned below) for Eclipse not to try to restore these editors when you restart Eclipse.
If you do not, you will get some exceptions, for example:

  Could not restore workbench layout Unable to restore editor - createElement returned null for input element factory: org.eclipse.ui.part.FileEditorInputFactory.

You need this preference (from this JavaTips ) - it does not close projects, but at least clears your workspace:

 > General > Editors > Close editors automatically 

When any eclipse workspace closes without closing all its editors and reopens the same workspace, it again opens all the editors that were open during the close.
This can slow down the launch of the eclipse.
Therefore, it is better to close all open editors before closing the workspace.

All open editors can be automatically closed by closing the eclipse workspace.

Answer 2

I think you can write a plugin to do this, but since you are the first person who seems to need it, nothing like this exists.

Answer 3

Is it possible to add an answer a few years later ... just discovered if you right-click on a project and close all unrelated projects, all projects that are not related to each other will still become a faster way to close all your projects.

If this is useful to anyone in the future ?:-)
