Des problèmes sont survenus lors de l'appel du code du plug-in: "org.Eclipse.jface"

J'ai un nouveau projet Java chez Eclipse de SVN et je viens d'essayer d'ouvrir le projet dans la fenêtre Explorateur de projets d'Eclipse.

Des problèmes sont survenus lors de l'appel du code à partir du plug-in: "org.Eclipse.jface".

Comment pourrais-je résoudre ce problème?

Votre projet peut être configuré pas pour votre composition. Essayez de supprimer .classpath et .project et de recréer le projet à partir de sources existantes. Supprimez également les répertoires internes d'Eclipse s'ils ont été validés par inadvertance sur le SVN, tels que .settings qui commence par point.

Fichier d'édition 

YouProject/.settings/org.Eclipse.wst.common.project.facet.core.xml

ajout de noeud

<fixed facet="jst.web"/>

peut résoudre le problème. Vous devez fermer et rouvrir le projet ou même supprimer le projet d’Eclipse (sans supprimer le contenu), puis Fichier/OpenProjectFromFilesystem pour le recharger.
