Packaging an executable fat JAR with Apache Maven

	Three ways to create an executable and fat JAR with Maven :

	maven-jar-plugin (it doesn't add dependencies inside the final JAR, they have to be in the classpath)

	Don't forget it goes between the build and plugins tags.

	<build>
	<plugins>
	<plugin>
	<groupId>org.apache.maven.plugins</groupId>
