Erreur d'initialisation au démarrage du printemps

J'utilise l'outil Spring Initialize pour générer un squelette de travail, .__ J'ai pris la valeur par défaut avec MAVEN PROJECT & Java & SPRING BOOT 2.0.0 

https://start.spring.io/

Quand je lance mvn clean install (sans faire de changement dans le projet), j'ai l'erreur suivante, une idée de comment la surmonter?

Probablement la dépendance que vous avez ajoutée

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-rest</artifactId>
    </dependency>

Il semble que la connexion à la base de données soit nécessaire lors de l'initialisation. Peut-être qu'une connexion à la base de données sur le fichier application.properties ou la suppression de cette dépendance jusqu'à la construction de la base de données peut vous aider.

Aussi, pour être sûr de la raison exacte, merci de partager votre fichier application.properties
