Java 9 Programming Blueprints

Bootstrapping the application

As noted in the introduction, this will be a JavaFX-based application, so we'll start by creating the skeleton for the application. This is a Java 9 application, and we intend to make use of the Java Module System. To do that, we need to create the module definition file, module-info.java, which resides in the root of our source tree. This being a Maven-based project, that would be src/main/java:
