Voici l'erreur que j'obtiens généralement lorsque ma connexion Internet est défaillante et que j'essaie de construire une application Web avec maven.
Ma question est la suivante : pourquoi maven doit-il toujours télécharger chaque fois que la même application a été construite auparavant ?
Qu'est-ce qui pourrait être faux dans ma configuration qui fait que maven télécharge à chaque fois ?
Voici l'erreur que je reçois lorsque j'essaie de construire hors ligne :
