[Maven2][hibernate3-maven-plugin][Version 2.2] hbm2cfgxml hbm2java annotationconfiguration

**sebago** · 07/07/2010, 15h45

Bonjour,

j'essaie d'utiliser le plugin hibernate3-maven-plugin (2.2) pour générer mes POJO (EJB3/Hibernate annotations).

Je souhaite génerer le fichier hibernate.cfg.xml (avec hbm2cfgxml), puis enchainer avec hbm2java.

Ci-dessous la partie plugins de mon pom :

Comment éviter les forked lifecycle, et comment ne plus avoir l'exception "Class not Found" ?

Merci d'avance pour votre aide.

Bonjour,

J'ai le même type de problème et j'ai du séparer (projet maven multi-modules) la génération du fichier de configuration Hibernate et les fichiers de mappings du la génération du code Java.
