I created a project with Spring Initializr in Maven, Java 17, Spring boot 3.0.0 with two dependencies : Spring Web and Spring Boot DevTools

i tried to run the main class and i have this error :

Erreur : impossible to find or charge the principal class src.main.java.com.packt.cardatabase.CardatabaseApplication caused by : java.lang.ClassNotFoundException: src.main.java.com.packt.cardatabase.CardatabaseApplication

I did change nothing in the code can you explain me the error please thanks you very much

CardatabaseApplication.java :

package com.packt.cardatabase;

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

@SpringBootApplication
public class CardatabaseApplication {

    public static void main(String[] args) {
        SpringApplication.run(CardatabaseApplication.class, args);
    }

}

" Now, if the project was executed correctly, you should see the started CardatabaseApplication class in the text at the end of the console. The following screenshot shows the content of the Eclipse console after our Spring Boot project has been started: "

Two things indicate to the real issue:

• The class CardatabaseApplication is defined in the com.packt.cardatabase database.
• This error message java.lang.ClassNotFoundException: src.main.java.com.packt.cardatabase.CardatabaseApplication.

Somehow, you need to remove src.main.java when you are running the class. I assume you are running this from your IDE, and a misconfiguration is causing this.
