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?
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.
