Maven, creating your own archetype. How to write package names in classes?

Question

Java

Good evening.
When creating my archetype in Maven, I encountered such a problem.
I set the structure of packages and classes. In classes, I prescribe the name of the packages through the $package variable. As a result, after creating a project from an archetype, the structure of packages and classes itself is created. But only the root name of the package is pulled into the class.
For example, I have a package:
com.project.utils.date
And in the class code it only pulls:
com.project
How to make the full name of the package be pulled into the class?
