How to migrate non-modular code into modules in the Java Module System

In the second part of his live coding session, developer Nicolai Parlog explains how to turn JARs into modules.

Packaging code into neat, well-defined units makes it easier to deliver safe and reliable applications. The Java Platform Module System is a language standard for creating these units. With modules, you can closely control how JARs interact and easily identify any missing dependencies at startup. This shift in design is so fundamental that starting with Java 9, all core Java APIs are distributed as modules, and libraries, frameworks, and applications will benefit from doing the same.

THANK YOU GOD, SAVED ME AFTER 6 HOURS

thanks for the overview. so how do I actually use a non-modular dependeny in my modular maven project? I have a modular project and added a non-modular dependency in the pom dependencies section. i don't get. i feel like java is more configuring and finding out work-arounds instead of writing software.

thanks anyway but your way of explaining is a mess
