[Pi2]

Bonjour,
je n'arrive pas à faire fonctionner le plugin Maven2 (version 0.0.9) sous Eclipse (version 3.1). (plugin récupéré de http://m2eclipse.codehaus.org/)
Lorsque, ayant sélectionné un projet, je clique droit et sélectionne :

Maven2 > Enable

j'obtiens l'erreur suivante:

The chosen operation is not currently available.

[jerrr]

Tu as quoi dans le journal des erreurs d'eclipse ?

[Pi2]

peux-tu me dire où se trouve le journal des erreurs? je ne connais pas.
Merci.
Pi2.

[otsgd]

Salut, il se trouve dans {workspace}/.metadata/.log

[jerrr]

Ou graphiquement dans éclipse faire : Fenêtre / Afficher la vue / Journal des erreurs

[Pi2]

Merci! En effet, on comprend mieux les erreurs tout de suite en regardant le fichier de log. :-)

Les voici (y'en a une petite pile!):

[jerrr]

Tu as quoi dans eclipse / fenêtre / préférences... / maven2 / Local Repository Folder ?

[otsgd]

Pas sur, mais as-tu définit dans les préférences l'emplacement de ton repository Maven ?

Edit : Grillé !

[JulienBalas]

Bonjour,
je n'arrive pas à faire fonctionner le plugin Maven2 (version 0.0.9) sous Eclipse (version 3.1). (plugin récupéré de http://m2eclipse.codehaus.org/)
Lorsque, ayant sélectionné un projet, je clique droit et sélectionne :

j'obtiens l'erreur suivante:

J'ai eu le même probleme, la solution que j'ai trouvé sur un forum US consiste a
1) installer maven
2) le lancer au moins une fois a la main en ligne de commande (par exemple creer un projet bidon)
3) relancer eclipse.

maintenant j'arrive a utiliser le plugin maven dans eclipse

[Pi2]

Merci beaucoup pour cette précieuse info. Je vais donc faire cela. Le problème étant qu'avec cette version d'eclipse, il ne trouve pas et ne permet pas de spécifier le repository pour maven. :-( Donc la soluton de le faire la première fois de façon extérieure résoud le pb. :-)
Merci beaucoup Julien!

[Pi2]

Ca marche!
Précision, le problème était que le repository maven ne pouvait pas être spécifié directement via l'interface eclipse.
Donc
1/ télécharger maven et installer maven (standalone en dehors d'eclipse)
2/ exécuter la commande:
<code>
mvn -Declipse.workspace=<path-to-eclipse-workspace> eclipse:add-maven-repo </code>
3/ relancer eclipseEt voilà!

[belrifou]

un petit détail à ajouter pour avoir eu le même problème :
Dans le fichier settings.xml dans <maven\conf> Il ne faut pas changer le repertoire repository de place. Sans quoi le plugin d'eclipse ne fonctionne pas.

[yesilay]

créer un dossier .m2 en linge de commande dans C:\Documents and Settings\{tonnomdutilisateur}\
et y mettre ton settings.xml
donc
C:\Documents and Settings\{tonnomdutilisateur}\.m2\settings.xml
