You can use Smart Saving. It's a plugin for Eclipse 4.

It saves periodically and also when the editor tab or Eclipse lose focus. You can change the settings to adapt to your need.
Question
Can eclipse be made to autosave files you have open and are working on AND do so without setting off any actions hooked onto saving?
Does the option at Windows > Preferences> General > Workspace > Workspace Save Interaval ( in minutes ) do this?
