If you want to save all the dirty editors before doing any project level operation (such as build/refactor), you might want to show the user the "Save Resources" dialog with the list of dirty editors. This tip tells you how to do that.
The first version of this tip had a roundabout way (read: nasty way) of doing it. Thanks to Boris for pointing the right API which does the trick.
PlatformUI.getWorkbench().saveAllEditors(true)
This returns a boolean value, in case the user presses Cancel button and you want to cancel the operation.
