maven-jigsaw-examples

For now I have two examples of modularized Java applications

1. standard-multi-modules: generates a 986MB Docker image to run a simple application
2. multi-modules-jmod-jlink: generates a 59MB Docker image to run the same application
3. fairy-tales: testing how to build the example in https://github.com/gradle-guides/building-java-9-modules in Maven
4. fairy-tales-jmod-jlink: another version of fairy-tales without Guava and using JMOD and JLink
5. modularized-args4j-usage: example on how a modularized library that needs to use reflection in the application's classes works with jmod and jlink.

Prerequisites

To run these examples, you must have installed:

• Java 11
• Maven 3.6.0
• Docker CE or EE

How to build

Firstly, you must clone the maven-jmod-plugin and maven-jlink-plugin repository to build the plugins:

For Maven JMOD plugin:

git clone https://github.com/apache/maven-jmod-plugin.git
cd maven-jmod-plugin

For Maven JLINK plugin:

git clone https://github.com/apache/maven-jlink-plugin.git
cd maven-jmod-plugin

and then build each plugin:

mvn clean install

Finally, you can select either of the projects to build.
