Spring Maven clean error - le profil demandé " pom.xml" n'a pas pu être activé car il n'existe pas

j'essaie de construire une botte de printemps *.la guerre avec maven, mais je reçois:

[WARNING] The requested profile "pom.xml" could not be activated because it does not exist.

après avoir lancé le mvn: clean.

Je ne sais pas pourquoi, je suis ce guide.

après le succès, maven génère un dossier cible dans le projet, il ne contient que le Manifeste.mf, pom.propriétés et pom.XML.

je suis un débutant utilisant maven / spring et je n'ai pas trouvé d'indices sur ce que il pourrait être. Toute aide serait appréciée.
