Helios ne démarre plus, après avoir mal fermé l'application

[Iori Yagami]

Bonjour,

Je crois que j'ai mis en veille la machine avant qu'Eclipse finisse sa fermeture. Résultat: le Workspace ne s'ouvre plus. voici l'erreur récupérée du Log (.metadata) :

Je peux faire un autre workspace, mais j'aimerais bien récupérer celui-là (trop de trucs de configuration à refaire). Donc, y a-t-il un moyen pour corriger l'erreur et récupérer le workspace ?

Merci d'avance pour votre aide.

[Deadpool]

salut.

Au pire tu crées un nouveau workspace et tu importes tes projets dedans.
Non?

Tu récupéreras au moins la config niveau projet si elle n'est pas corrompue.

[Iori Yagami]

Les librairies (user libraries) par exemple sont associées au workspace, y en a beaucoup, et parfois j'oublie quelle librairie est elle associée à tel ou tel projet.
Bref, j'ai dû créer un nouveau workspace et ça m'a couté du temps. Cela dit, je laisse le sujet ouvert parce que ça arrivera une autre fois, même si c'est pas à moi, ce sera pour un autre.. peut être quelqu'un sait comment récupérer un workspace.

Lancer eclipse avec l'option -clean peut parfois régler certains problèmes.
