dev de plugin Ant pour Maven 2

Version imprimable

suite a une discussion je suis en train d'etudier le developpement d'un plugin Ant pour Maven
en suivant le tutoriel suivant.
Malheureusement pour la premiere partie ("Getting started : Hello World") j'ai deja des probleme :
Apres avoir creer les fichiers "hello.build.xml","hello.mojos.xml" et "pom.xml":
je peux lancer la commande "mvn -U install" --> jusque la pas de probleme, il m'installe bien mon plugin
../.m2\repository\plugins\hello-plugin\1.0-SNAPSHOT\hello-plugin-1.0-SNAPSHOT.jar

Mais ensuite en lancant la commande "mvn org.myproject.plugins:hello-plugin:hello"
j'ai une erreur

Tu es sur de ce repertoire? Ca ne me parait pas être le bon? A mon avis, il manque de groupId ce truc....

Mais ensuite en lancant la commande "mvn org.myproject.plugins:hello-plugin:hello"
