Which version of Maven, and which maven.plugin.validation setting, are you using?
I cannot reproduce this warning with Maven 3.9.3 (I happen to locally still have Maven 3.8, so without plugin validation, explaining why I had never seen any similar warning; I'm thus trying to reproduce with a Docker image, and Docker Hub currently is still 3.9.3, not 3.9.4)
I do have a warning about localRepository in gwt:test (inherited from Surefire, that will have to be updated some day) but not about the dependency scopes.
