• *Nix,
• Windows NT
• Java Service Wrapper

• appassembler:assemble qui permet de créer une arborescence de fichiers comprenant des scripts de lancement de l’application ainsi que de toutes les dépendances nécessaires à son exécution.
• appassembler:create-repository qui permet de créer le répertoire contenant toutes les librairies nécessaires au bon fonctionnement de l’application.
• appassembler:generate-daemons qui permet de créer une arborescence de fichiers comprenant des scripts et des librairies à utiliser pour wrapper l’application dans un service via Java Service Wrapper.

package fr.soat.maven.sample;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

public class FooClass {

private static final Logger LOGGER = LoggerFactory.getLogger(FooClass.class);

public static void main(String[] args) {
LOGGER.info("this is FooClass sample");
}
}

Cet exemple a pour objectif de montrer, dans un premier temps, ce que génère le goal assemble puis, dans un second temps, le goal generate-daemons.

Pour ce faire, le pom.xml suivant sera utilisé :
