J'essaie de lancer un petit programme de démarrage Spring sur ma machine et lorsque je lance clean compile
(même avant d'essayer spring-boot: run) sur maven, l'erreur suivante apparaît:

Et voici ma classe Java:
package com.benayed.spboot.poc.SpringBootPoc;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
@SpringBootApplication
public class SpringBootPocApplication {
public static void main(String[] args) {
SpringApplication.run(SpringBootPocApplication.class, args);
}
}
J'ai essayé de nombreuses solutions que je pouvais trouver sur Internet, telles que la suppression du référentiel .m2, l'ajout de différentes balises (version, fork, ...) au plugin spring-boot-maven-plugin
qui, j'en suis à peu près sûr, est à l'origine du problème.
Aucune suggestion ?
Vous avez 0 dépendances de compilation, seules les dépendances test-compilation sont définies, car vous avez commenté spring-boot-starter-data-jpa
. Les démarreurs Spring attirent d’autres dépendances (y compris d’autres démarreurs) pour créer tout le nécessaire au moment de la compilation. Décommentez la dépendance spring-boot-starter-data-jpa
et/ou réexaminez les dépendances que vous souhaitez réellement.
Vous devez ajouter cette dépendance
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
alors ça va marcher.
Ajoutez la section ci-dessous en dehors de la gestion des dépendances et effectuez une mise à jour du projet. Et puis l'installation propre de Maven.
<parent>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-parent</artifactId>
<version>1.5.10.RELEASE</version>
</parent>
Et la dépendance ci-dessous.
<dependency>
<groupId>org.springframework.boot</groupId>
<artifactId>spring-boot-starter-web</artifactId>
</dependency>
Si le problème persiste (non susceptible de se produire), ajoutez les autres dépendances mentionnées ici
