It's the simplest example of using java modules.
The repo was created for the purpose of the article Quick introduction to Java 9 modularization
and contains two modules pl.tfij.java9modules.app and pl.tfij.java9modules.greetings.
The first one has a dependency to the second one.
Each module contains only one class with a one single-line method.
This project has been modified from the original to demonstrate Log4j working as modules in Java 9.
Included scripts allow to easily run the code.
To compile the code just start a compile.sh script.
Then execute the package.sh to build jar files.
Finally run run.sh to start the main class from the pl.tfij.java9modules.app module.
Additionally, linking.sh builds executable pack which contains only required java libs
(compile and package the code using compile.sh and package.sh before running this script).
A script 'run-linked.sh' launches main class from this pack.
The result is the same as running a run.sh script.
