Vaadin 7 works with Maven how to prevent style.css from changing style

I am using vaadin 7 and I am building it with maven.

There is a CSS file called 'the_name_of_myProject' / src / main / webapp / VAADIN / themes / mytheme / styles.css If I modify it in any way, my modifications are overridden by the next maven assembly. It seems that the file is always regenerated from cans.

What should I do if I want these modifications to survive?

I created my own theme with a different name, but that did not help, because its .css were redefined the same way.

Any advice is appreciated.
