Vaadin 7 build with Maven, how to prevent style.css from being always re-generated

Question

I use vaadin 7 and I build 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 build. Looks like the file is always re-generated from jars.

What can I do if I want those modifications to survive?

I have created my own theme with a different name but it did not help either because its .css were overridden in the same way.

Any advice is appreciated.

Sass is an extension of CSS. Here is a description: link
Maven generates CSS from Sass. You can put your custom css code into styles.scss.
