I am trying to remove a few classes from a dependency. I have tried using the following configuration in the pom.xml file but it is not working. The classes are still present in the fat jar. Can anyone help me with this?

I thought maybe they are present during the compile time, so I tried package but they are still present.

My intention is to remove the Event and BaseEvent classes from the models dependency.

It will even work for me if we can specifically include only the classes I want to include. Let’s say I want to keep all dto in the below structure and remove all entity classes, and specifically EventEntity class.

models
 - dto
   - EventDto
   - SomeOtherDto
   - AnotherDto
   - YetAnotherDto
 - entity
   - EventEntity
   - SomeOtherEntity
   - AnotherEntity
   - YetAnotherEntity

Any help will be appreciated. Thanks in advance.
