How to disable auto formatting upon save in Eclipse?

Question

Eclipse keeps auto formatting upon save, for example: it is insisting the following code should be in a single line once I save, despite breaking it up the way I want to.

If you wish to keep the auto-formatter, but don't want this behavior, you can also configure it in the fomatter :

right click on the project -> properties -> java code style -> formatter

(If you don't have a project specific formatter the global configuration can be accessed this way : Window -> Preference -> Java -> Code Style -> Formatter).

Edit... the active profile, open the Line Wrapping tab, and there check the Never join already wrapped lines option.

This option is there at least since eclipse Luna

Here is a screenshot where this option is :
