Dependency dep = resolutionServices.dependencyHandler.create("dummyGroupId:dummyArtifactId:dummyVersion")

        then:
        ResolveException e = thrown()
        def stacktrace = ExceptionUtil.printStackTrace(e)

The ability to change the allowed usage of a configuration after creation will be removed in Gradle 9.0.
