[Eclipse] An error has occured

[ShE3py]

Bonjour,
Je viens de lancer Eclipse, mais quand je choisis le Workspace il me dit "An error has occured. See the log file blabla\.metadata\.log"

Donc voici le .log

Si je voit l'erreur, il me dit que le workspace est incompactible ; j'avais Eclipse Mars quand j'ai commencé et je suis passé la semaine dernière à Eclipse Néon, et je pouvais charger le projet de l'ancienne version sans soucis jusqu'à aujourd'hui.

Merci pour vos réponses,
ShE3py.

Bien le bonsoir en ce bas monde,

Comme c'est si bien écrit dans tes logs, ton espace de travail a été sauvegardé dans une version incompatible avec ta version actuelle. Il faut donc que tu convertisse ton ancien workspace au nouveau format.
Je te conseille ce lien, qui te donne toutes les étapes http://help.eclipse.org/mars/index.jsp?topic=/org.eclipse.platform.doc.user/tasks/tasks-2.htm

Bien cordialement,

J'ai un peu lu, faut mettre l'argument -data (les paramètres derrières je sait pas) mais ont peut pas run eclipse avec "java -jar eclipse.exe -data" car c'est un .exe pas un .jar

 

[Noucho]

Et tu n'as pas moyen de convertir ton exe en jar ?

Bien cordialement,
Noucho
