Erreur "R cannot be resolved to a variable"

Bonjour,
J'essaie de réimporter un projet Android existant mais j'ai comme erreur "R cannot be resolved to a variable".
J'ai cleané plusieurs fois mon projet, re buildé, rien n'y fais :?

Le compilateur me renvoie aussi une erreur "Errors running builder 'Android Pre Compiler' on project 'Nom_du_projet'"

Voici le log complet :

Code:

Quelqu'un a t'il une solution ? Merci d'avance

Bonjour,

Si tu as des dossiers svn supprimes les :D.

Tu peux regarder dans les logs du pré compil voir ce qu'il t'annonce aussi. Ce fichier se trouve a la racine de ton workspace il me semble

Effectivement, j'avais des .svn qui trainaient, mais ce n'étais apparemment pas le problème. j'ai du réinstaller eclipse entièrement pour que cela refonctionne.

De mon côté j'avais eu le même problème et le fait de supprimer les dossiers svn avait corriger le souci sur un pc ;).
