Answer 1

It sounds like you're trying to import a package that contains no classes, but only contains sub-packages.

i.e. You have classes in com.company.functions - e.g. com.company.functions.Foo
But no classes directly in com.company - e.g. com.company.Bar

Despite that fact that java packages appear to be hierarchical, for the purposes of imports, they aren't.

So, you cannot import com.company.* because it contains no classes of its own.
You can import com.company.functions.* because it does contain classes
And you can import com.company.functions.Foo because that is a class.

Now, you might be tempted create a Bar class in com.company. That would allow you to import com.company.*
But because imports are not treated hierarchically, that wouldn't cause classes in com.company.functions to be imported
You would still need to explictly import com.company.functions.Foo, or wildcard import com.company.functions.*
