I'm trying to write an ArchUnit test rule, which should ensure that interfaces annotated with @ComponentInterface annotation have method parameters annotated with @Input annotation. Like this:

ArchRule rule =
        methods()
            .that()
            .areDeclaredInClassesThat()
            .areInterfaces()
            .and()
            .areDeclaredInClassesThat()
            .areAnnotatedWith(ComponentInterface.class)
            .should()
            .haveRawParameterTypes(
                allElements(CanBeAnnotated.Predicates.annotatedWith(Input.class)));

The interface looks like this:

@ComponentInterface
public interface AdminComponent {
  void login(@Input(name = "loginString") String loginString);
}

But the test fails with an error like this: Method < com.some.package.AdminComponent.login(java.lang.String)> does not have raw parameter types all elements annotated with @Input in (AdminComponent.java:0)

How should the rule look like to work properly in this case?

P.S. After doing some debug, it turned out that haveRawParameterTypes checks if parameter types (classes) are annotated, not the method parameters itself. So it looks at String class and finds out, that it is not annotated with @Input. Good to know, but it doesn't solve the problem.
