Échec de la configuration d'un DataSource: l'attribut 'url' n'est pas spécifié et aucune source de données intégrée n'a pu être configurée. PRINTEMPS

J'ai déjà vérifié toutes les questions similaires et chaque réponse indique que je dois spécifier un driverClassName, ce que je fais déjà. Voici mon application.yml:

spring:
  application:
    name: cibus-backend
  datasource:
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/Cibus?useSSL=true
    username: root
    password: 1234567890
  jpa:
    show-sql: true
    hibernate:
      ddl-auto: update
      properties:
      hibernate:
        format_sql: true
        type: trace
    database-platform: org.hibernate.dialect.MySQL5InnoDBDialect
    database: mysql
logging:
  level:
    org:
      hibernate:
        type: trace

Est-ce que je manque quelque chose? La chose étrange est qu'un de mes camarades de classe qui a le même code peut parfaitement démarrer l'application. C'est pourquoi je pense que cela a quelque chose à voir avec le chemin. Peut-être que spring n'accède pas au fichier yml. Je l'ai inclus dans src.main.resources, qui est l'emplacement par défaut où Spring le recherche . Voici le stacktrace:

Error starting ApplicationContext. To display the conditions report re-run         
your application with 'debug' enabled.
2018-10-21 10:13:15.657 ERROR 10356 --- [JavaFX-Launcher]             
o.s.b.d.LoggingFailureAnalysisReporter   : 

***************************
APPLICATION FAILED TO START
***************************

Description:

Failed to configure a DataSource: 'url' attribute is not specified and no embedded datasource could be configured.

Reason: Failed to determine a suitable driver class


Action:

Consider the following:
    If you want an embedded database (H2, HSQL or Derby), please put it on the classpath.
    If you have database settings to be loaded from a particular profile you may need to activate it (no profiles are currently active).

Exception running application labtic.AppStarter

Voici la Gradle Build car on m'a demandé de l'inclure:

buildscript {
    ext {
        springBootVersion = '2.0.5.RELEASE'
    }
    repositories {
        mavenCentral()
    }
    dependencies {
        classpath("org.springframework.boot:spring-boot-gradle-plugin:${springBootVersion}")
    }
}

apply plugin: 'Java'
apply plugin: 'Eclipse'
apply plugin: 'org.springframework.boot'
apply plugin: 'io.spring.dependency-management'

group = ''
version = '0.0.1-SNAPSHOT'
sourceCompatibility = 1.8
repositories {
    mavenCentral()
    jcenter()
}


dependencies {
    compile('org.springframework.boot:spring-boot-starter-data-jpa')
    runtime('mysql:mysql-connector-Java')
    testCompile('org.springframework.boot:spring-boot-starter-test')
    // https://mvnrepository.com/artifact/mysql/mysql-connector-Java
    compile group: 'mysql', name: 'mysql-connector-Java', version: '8.0.12'

    compileOnly 'org.projectlombok:lombok:1.18.2'
    annotationProcessor "org.projectlombok:lombok:1.18.2"
}

Des idées? Merci d'avance.

Pour réparer le 

Impossible de déterminer une erreur de base de données intégrée

Essayez d'exclure la configuration automatique de DataSource dans la classe d'application Spring Boot. Vous pouvez le faire en utilisant EnableAutoConfiguration  

@EnableAutoConfiguration(exclude={DataSourceAutoConfiguration.class})
@SpringBootApplication
public class {...}

Le format de votre fichier yml n’est pas correct, remplacez les lignes de début par

spring:
  ...
  datasource:
    driverClassName: com.mysql.cj.jdbc.Driver
    url: jdbc:mysql://localhost:3306/Cibus?useSSL=true
    username: root
    password: 1234567890

Conservez ce format d'espaces au besoin dans tout le fichier

Pour Spring Boot avec JPA et Hibernate use exemple:

spring.datasource.type = com.zaxxer.hikari.HikariDataSource spring.datasource.url = jdbc: postgresql: // localhost: 5432/somedb
