The Java Module System in practice (Serban Iordache, Germany)

jeeconf.com/pr...
Java 9 introduced modules as first-class citizens that represents a higher level of aggregation above packages. They allow you to implement more robust software systems by providing stability, cohesiveness, encapsulation, and isolation.
Modularizing a ‘Hello world’ application is pretty straightforward, but it provides only limited benefits. That’s because the primary strength of modularization lies in its ability to impose a clear structure on large codebases. However, modularizing a large codebase is not a trivial task.
In this talk, we will discuss the difficulties encountered when implementing a real-life modular application and how to overcome them. We will also focus on the usage of build tools such as Gradle and Maven to compile, test, build and run modular applications. In addition, we will explore a series of plugins that automate tasks such as:
- creating modular jars that target a Java release before 9
- using JavaFX in Java 11+ applications
- creating custom runtime images
- packaging native installers using the jpackage tool introduced in Java 13
The presentation will include both talking and live coding.

Here's one virtual session about it kzbin.info/www/bejne/n3vcqqaVgcx6Y7c
