When maven-antrun-plugin artifact id is defined twice in a pom, only second one is executed.

Could Maven give a verbose warning that the maven-antrun-plugin artifact id is defined twice in a pom and that only second one is executed? While it is probably a user error to define such a thing twice in a pom (clearly, multiple executions ought to be created within a single maven-antrun-plugin definition) it would be helpful if Maven would give a warning, perhaps something along the lines of, "Please do not define multiple instances of the same artifact Id." instead of just skipping over the first and running the second.
