maven, JDO et classPath

**xixi31** · 11/04/2007, 20h45

Bonjour,

Voilà, j'ai un petit projet dans lequel j'essaie vainement d'enhancer certaines classes via le plugin JPox.

J'ai une classe sous src/main/java/org/blackdog/type/AudioItem.java.
J'ai placé un fichier jdo sous src/main/resources/org/blackdog/type/AudioItem.jdo. Il ressemble à ca :

Code :

<?xml version="1.0"?>
<!DOCTYPE jdo PUBLIC 
    "-//Sun Microsystems, Inc.//DTD Java Data Objects Metadata 2.0//EN" 
    "http://java.sun.com/dtd/jdo_2_0.dtd">
<jdo>
    <package name="org.blackdog.type">
        <class name="AudioItem" identity-type="datastore">
            <primary-key name="id" column="id"/>
            <field name="name" persistence-modifier="persistent"/>
            <field name="category" persistence-modifier="persistent"/>
        </class>
    </package>
</jdo>

Ce dernier fichier est bien considéré lors de l'appel au plugin jpox. J'ai la trace suivante lors de l'éxécution :

JPOX Enhancer completed with success for 0 classes. Consult the log for full details

Visiblement, Il semble que le répertorie contenant les sources compilés soit bien présent dans le classpath considéré par maven (voir ligne 3) !

Peut-être que la façon d'appeler la tâche jpox est erronée. Voici ce que j'ai ajouté dans le pom.xml de manière à ce que la tâche d'enhancement soit appelé après la compilation des classes :

Code :

                    </execution>
                </executions>
            </plugin>

Bref, un peu paumé... quelqu'un a t-il déjà rencontré ce problème? ou avez vous déjà utilisez un autre plugin pour faire de l'enhancement de classes JDO?

ps : petite précision, j'utilise maven 2.0.5

Le plugin est déjà attaché à une phase, laisse le sur cette phase qui est process-classes:

Merci pour le coup de main evenisse..

Ok, ca commence à aller un peu mieux... (boulet que je suis... le nom de la classe était erroné)...
malgré tout, je reste sur un message d'erreur relativement similaire :

Cette classe (org/blackdog/type/AudioItem.class) existe?
Tu peux essayer de lancer maven en mode debug (-X), tu auras peux-être plus d'info.

Visiblement, pas de traces DEBUG intéressantes concernant l'éxécution de JPox...

Le fichier class existe bel et bien...

J'ai envoyé un mail sur la mailing liste de http://mojo.codehaus.org/jpox-maven-plugin/ mais visiblement, le sujet n'a pas l'air de passionner les foules....

Y'a t-il un autre plugin pour enhancer des classes sous maven ??

**evenisse** · 13/04/2007, 13h47

Bon, dernière idée. Est-ce que ta classe utilises un type qui ne serait pas définit dans ton fichier jdo?

Je crois qu'il existe un autre plugin pour enhancer les classes chez jpox.
As-tu essayer l'enhancer de jpox en ligne de commande pour voir si le pb persiste?

**xixi31** · 13/04/2007, 14h04

J'ai essayé de ne placer dans le fichier jdo que des attributs de base (int & string) mais ca n'a rien changé au problème. J'essaierai de le faire à la main... voir si le problème persiste.

JPox met effectivement à disposition un plugin maven pour enhancer des classes mais il n'est utilisable que sous maven 1... (http://www.jpox.org/docs/1_1/tutorials/maven.html)

Je vais aussi essayer de tester avec un projet simple sous ant.

Merci pour le coup de main.

**evenisse** · 13/04/2007, 14h15

Pour maven2: http://www.jpox.org/docs/1_1/enhancer.html#maven2

**xixi31** · 13/04/2007, 14h21

... autant pour moi...

je vais tester celui-là aussi !

**xixi31** · 13/04/2007, 21h08

J'ai testé avec une classe toute simple dérivant d'Object --> enhancement réussi !!!!!

Apparemment, le problème venait du fait que la classe que je voulais rendre PersistenceCapable dérivait d'une autre classe....

Quoi qu'il en soit, peut importe le plugin utilisé ( celui de codehaus ou directement celui indiqué par evenisse ), l'enhancement fonctionne....

Etonnant que le message d'erreur soit si obscure.

Encore une fois, merci evenisse pour le support.

maven, JDO et classPath
