How can I easily fix Checkstyle errors?

Question

Is there a way to have an IDE fix Checkstyle errors automatically without having to fix each manually?

Answer 1

There is a way to do this every time you save your file but not all warnings in Checkstyle can be fixed automatically.

You can have Checkstyle generate a formatter for you by right clicking on your package in the Package/Project explorer and selecting Checkstyle->Create Formatter-Profile. This will create a new formatter called eclipse-cs [your-package-name] based off of your Checkstyle configuration. You'll find it in the "Active profile" drop-down in the formatter preferences of Eclipse.

You can then set the formatter to run each save by going to Preferences->[Language of Choice]->Editor->Save Actions. Check the "Perform the selected actions on save" and "Format source code" boxes.
