How to format all Java files in an Eclipse project at one time?

Question

I have an old Eclipse project and the code is not well formatted. I'd like to format all the .java files according to the settings in Eclipse. I don't want to edit every individual file with Ctrl+Shift+F. Is there a way to format all my files? Perhaps an Eclipse plugin?

Answer 1

Right click on the project root and select Source -> Format. This should work for at least version 3.8.1. and above.

If the above does not work, you're probably using an older Eclipse-version. In such case you can select your Source Folders by clicking on them while holding down CTRL, then select Source -> Format from the right-click -menu. Works with package-folders and class files also, in case you don't want to format the entire project.
