Can you organize imports for an entire project in eclipse with a keystroke?

Select the project in the package explorer and press Ctrl + Shift + O (same keystroke as the single class version). Should work for packages, etc.

You can edit the clean up options on save to make it organize imports. That way all of your imports will always be organized.

In eclipse 3.4 just go into Window - Preferences. In the tree view look under Java -- Editor -- Save Actions.

This is how I keep my imports organized all of the time.

For Eclipse Helios, open the "Project Explorer" view, clic right on your src folder, go under the source menu, and clic "organize imports" that should work for all your project. or just hit the combination Ctrl + Shift + O on the src folder.
