This is the wrong place to report this, see also https://github.com/spring-projects/spring-framework/issues/32220#issuecomment-1933486294.

There's nothing wrong having an XSD using https. You're showing an issue in your IDE but that doesn't mean the source is wrong. If you need support for that, please ask on StackOverflow.

No problem. I know how to fix this. Just thinking about those who don't know having to correct something something that the IDE itself (Spring Tool Suite) doesn't recognize, which it should. But it's fine. Thank you.
