Check that your @Theme annotation theme name matches theme folder name src/main/VAADIN/themes and that there is correctly named .scss file like in this picture. I assume (based on the error message) you are using IDE plugin instead of maven to compile the theme. So you need to have the folder / theme file selected, when you when clicking the "paint"-icon of the plugin that triggers the theme compilation.
