Inject different types of the same class

I'm doing an exercise with @Inject of package javax.inject and I have no problem for example when in a class I think something like this

public class Persona {
    @Inject 
    private Rol rol;
}

but when I try to do the following, it shows me that it is ambiguous

public class Persona {
    @Inject 
    private Rol rol;
    @Inject 
    private List<Rol> roles;
}

I know I can use Qualifiers but the issue is that it's the same class I want to have role as a single object and roles as multiple role objects,

So far I only inject the single object and the list of roles initialize it in the normal way

List<Rol> roles = new ArrayList<>();
