Le déploiement d'un échantillon Web Spring MVC projet

Je suis nouveau sur Tomcat, Maven et Web Spring MVC (cadre v3 pour être précis). J'ai essayé de construire le exemple projet mvc-basic pour que je puisse déployer généré le fichier WAR sur un serveur de test (pas en local) et d'en analyser les effets.

Quand je lance Maven dans le répertoire contenant pom.xml, je vois ces vagues de messages d'erreur.

J'ai peu ou pas de connaissances sur les choses mentionnées par le compilateur. Comment puis-je générer le fichier WAR? Quels outils ai-je raté?
