Do .jar (Maven) build framework classes that are not used?

Question

Java

There is a library (framework) that contains many classes. If you use only a few classes from this library, will the rest that are not used be collected in a .jar project?

Answer 1

By default, Maven does not package classes from libraries into the final jar. There are a number of plug-ins that allow you to achieve packaging of classes from the libraries used or jar files of libraries as a whole. There are also separate plugins to select only the necessary classes.
