Springboot with Maven: Failed to configure a DataSource: 'url'

Question

I need to add a MySQL database in my springboot application(using Maven)

However when I run the project in Eclipse I get:

***************************
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

I already checked all these:

• The database, specified in the application.properties, exists
• Credentials/ url in the application.properties are correct
• Mysql server is running
• The dependency mysql-connector-j is included in the pom.xml
• mysql-connector-j-8.031.jar is included in the Maven Dependencies

I am using:

• java version "17.0.6" 2023-01-17 LTS
• Apache Maven 3.6.3
• Eclipse Version: 2022-12 (4.26.0)

MyProjectApplication.java

package com.springboot;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication()
public class MyProjectApplication {

    public static void main(String[] args) {
        SpringApplication.run(MyProjectApplication.class, "--debug");
    }

}

I also follow the default spring structure.
