In a Vaadin 8.1.5 app created with the Maven archetype named vaadin-archetype-widget where I briefly the file in the demo app module > src > main > webapp > VAADIN > themes > demo > styles.scss, I get these errors reported by IntelliJ 2017.2:

Error:(1, 13) Cannot resolve directory 'valo'

Error:(1, 18) Cannot resolve file 'valo.scss'

…regarding this content:

@import "../valo/valo.scss";

$gray: #d1d1cf;
$green: #40b527;
$darkgreen: darken($green, 30%);
…

Is this a real error?

  • Is that line a remnant of previous versions of Vaadin?
  • Or do that valo folder and valo.scss file appear at build time, so not a real problem?

Even after building, perusing the target folder does not reveal an nested valo folder. I do see target > my-app-1.0-SNAPSHOT > VAADIN > themes > demo > styles.scss. This leads me to believe this may be a mistake left in the Maven archetype's artifacts from previous versions of Vaadin.

This is no real error, this is IntelliJ not getting the big picture here (or like any IDE in most cases). The authority of right or wrong here is the SASS-Compiler of Vaadin (which is either ran on request while in dev mode or by your build tool) and that will look up things on the classpath, while IntelliJ will try to find those on the actual directories.

That nested valo folder will be found at runtime in the com.vaadin:vaadin-themes jar.
