how to create jar of java package in intelliJ idea

问题

I need to create a jar with compiled classes from a package which is inside of the module. I have a jar file which is actually a package inside of the module and I need to re-create it.

I can create jar of the whole module but I could not create the jar file of the package. How can I do that on idea?
