How do I retrieve all classes from a package in the neatest way possible?

First off, I want to say that I read this StackOverflow post

My current understanding is that if you want to get all classes from a package without writing a ton of code lines, you are basically stuck with the Reflections API. Here are some of the options:

Option 1.

    private static Set<Class<?>> getClassesFromPackage(String packageName) {
        Reflections reflections = new Reflections(packageName, new SubTypesScanner(false));
        return new HashSet<>(reflections.getSubTypesOf(Object.class));
    }

Not optimal: SubTypesScanner is deprecated so you'll get a warning

Option 2.

    private static Set<Class<?>> getClassesFromPackage(String packageName) {
        Reflections reflections = new Reflections(packageName, Scanners.SubTypes.filterResultsBy(s -> true));
        return new HashSet<>(reflections.getSubTypesOf(Object.class));
    }

Not optimal: Scanners.SubTypes.filterResultsBy(s -> true) is clumsy AF so you either get code that is not easily readable or you have to provide some meta commentary

    private static Set<Class<?>> getClassesFromPackage(String packageName) {
        Reflections reflections = new Reflections(packageName, getStuffThatMakesItWork());
        return new HashSet<>(reflections.getSubTypesOf(Object.class));
    }

    private static Scanners getStuffThatMakesItWork() {
        return Scanners.SubTypes.filterResultsBy(s -> true);
    }

Wouldn't it be peachy if I could write just this

    private static Set<Class<?>> getClassesFromPackage(String packageName) {
        Reflections reflections = new Reflections(packageName);
        return new HashSet<>(reflections.getSubTypesOf(Object.class));
    }

It is so much more readable, but sadly it doesn't work (the returned set would contain zero items)

What is the best way to scan for package classes?

Criteria:

1. The code should be as short as possible.
2. The code should be readable (a random person shouldn't get any WTF moments when looking at it)
3. You shouldn't get warnings

One thing I haven't mentioned yet is that the whole Reflections library is not maintained since 2021 so it may not be a solid long-term solution to rely on it. Are there alternatives that are at least just as good?
