S4662 issue with @use


We have Sonarqube 10.3 installed in our server and when analyze a project with scss files it throws s4662 issue.

The line with issue is:
@use '@angular/material' as mat;

But that line is ok according to material documentation:

I asume it’s a false positive. Could you check this please?

Thank you!

Hello pemola,

You are right, the @use rule that you mention is perfectly valid and should not be flagged as an issue. That said, I was not able to reproduce the problem. Can you please tell us more about your SonarQube setup and your project?

  • The build of SonarQube 10.3 you are using
  • The name of the SASS file that exhibits the issue
  • The path of this SASS file relative to your project root

Thanks in advance,



The Issue is in one of our angular projects.

  • Build of Sonarqube:
  • Name of the Sass file: themeMG.scss
  • Path: src/app/shared/theme/themeMG.scss

I hope this helps you to solve the problem :wink:

Thank you very much

Hello pemola,

Thanks for the information. We checked internally and I can confirm that the @use at-rule is whitelisted in the “Sonar way” default Quality Profile. Can you please check if your project is using a custom Quality Profile that does not whitelist this at-rule?

You can easily check this by clicking on the Rules tab, searching for “S4662” and looking at the list of Quality profiles that this rule is included in. Typically, I was able to reproduce your issue by creating a custom Quality profile and removing the “use” token from the ignoreAtRules parameter, as you can see in the following screenshots:

Yes, we use a custom quality profile and I have checked that “use” isn’t whitelisted in.

Thank you very much for your quickly resolution.

You’re welcome, I’m glad your issue was solved.
