Problème pour le Site éditorial riche

Bonjour
J'ai récupérer le pom.xml du Site éditorial riche que propose Lutece Webapp Store.
J'ai généré le site avec la commande :
clean lutece:site-assembly

J'ai créé une base de test en utilisant build.xml avec Ant.

Mais lorsque je démarre mon tomcat, j'ai l'erreur suivante:
