Bonjour,

J'ai crée un projet maven de type webapp qui contient de base un seul source folder : src/main/resources.

J'ai crée un second source folder : src/test/java, où j'ai crée un package pour y mettre un fichier java de test.

J'utilise le plugin maven "maven-war-plugin" et depuis que je viens de crée ce second source folder, je ne peux plus créer de fichier war.

C:\projets\pv-editique-rules>mvn -e package
+ Error stacktraces are turned on.

Avez-vous une idée, de comment pouvoir recréer un war après avoir ajouté un source folder à un projet maven de type webapp?

Merci :-)

Ton erreur semble plutôt venir du fait que le plugin de compilation est paramétré pour compiler en Java 6 alors que la version de Java que tu utilises est inférieure (1.5 ?).

Solutions possibles :

• Faire pointer ta variable d'environnement JAVA_HOME vers une JDK6
• Re-configurer le plugin de compilation avec des valeurs adaptées, par exemple :
  

  Code :

  Sélectionner tout - Visualiser dans une fenêtre à part
