Hello,
je developpe une architecture multi-tier ticket, project composé de 5 modules:
- ticket-batch
- ticket-business
- ticker-consumer
- ticker-model
- ticket-webapp

voici ici le shéma de mon architecture:
Pièce jointe 372614

mais pour les modules pom.xml, je ne comprends pas très bien la relation parent, et maven me renvoie des erreurs:

pom.xml de ticker-business :

Dans le pom.xml du ticket-model, j'ai défini les dépendances parentes avec junit
