"Failed to determine a suitable driver class" with Spring Boot / Java project when running compiled jar. But works fine in vscode – Postgresql

I’m making a REST API in Java using Spring Boot. And I’m encountering an issue that I don’t understand : when I run my code through vscode, everything works just fine. But when I try to run the compiled .jar file, I get the following error message :

<message>org.springframework.beans.factory.UnsatisfiedDependencyException: Error creating bean with name 'org.springframework.boot.autoconfigure.orm.jpa.HibernateJpaConfiguration': Unsatisfied dependency expressed through constructor parameter 0: Error creating bean with name 'dataSource' defined in class path resource [org/springframework/boot/autoconfigure/jdbc/DataSourceConfiguration$Hikari.class]: Failed to instantiate [com.zaxxer.hikari.HikariDataSource]: Factory method 'dataSource' threw exception with message: Failed to determine a suitable driver class</message>
    <frame>
      <class>org.springframework.beans.factory.support.ConstructorResolver</class>
      <method>createArgumentArray</method>
      <line>798</line>
    </frame>

It is a PostgrSQL database.

I guess that something is probably wrong with my pom.xml file ?

And here’s my application.properties file :

spring.datasource.username = [USER]
spring.datasource.password = [PASSWORD]
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.PostgreSQLDialect
spring.datasource.driver-class-name=org.postgresql.Driver
server.port = 8080
logging.level.org.springframework.web=DEBUG
logging.level.org.hibernate=ERROR

Thank you for reading ! If you had any ideas, I’ll be really thankful for your help !
I wish you all an excellent day !

EDIT : I’ve modifier the part of postgresql dependency in the pom.xml file. I now have the following :

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
</dependency>

But I’m still getting the same error…
