(maven 3,eclipse) substance : ClassNotFoundException

**olivier57b** · 05/06/2011, 04h15

bonjour,

je suis débutant avec maven et j'ai un petit problème avec maven; j'ai créé d'abord un projet à partir d'eclipse, un projet maven.
j'ai ajouté une JFRAME swing dans ce projet et ai défini la classe à lancer.
un petit "maven install" et j'ai pu obtenir ma fenêtre via un "java -jar monappli.jar".

ensuite, et parce que j'aime bien le gestionnaire de look-and-feel "substance", j'ai essayé de l'inclure dans mon projet, le projet étant disponible sur le repo central de maven.

et là, impossible de lancer le jar.
pourtant j'ai un "build successfull" lorsque je lance "maven install" à partir d'eclipse.
enfin, j'avais, car j'ai fait quelques modifs depuis et maintenant àa ne marche plus.

voici quelques bouts de code:

pom.xml
