intellj IDEA doesnt build jar properly

Question

I followed this "tutorial" to build a jar from a project in intellj. The project includes a small spring application, that works running from intellij itself.

If I build the jar and run it from the command line, it says "Error: Could not find or load main class". If I run the main.class file using java .\main.class, the same Message shows up.

I specified the Main class in Intellij-IDEA before building the Jar, and the Main.java file looks something like this:

@SpringBootApplication
@RestController
public class Main {

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


    @GetMapping("/index")
    public String index() {
           . . . .
    }
}

So I created a new project

I left the default options

not work

test with the build provided in spring boot

open command prompt, place yourself in the application directory, and run the following command : nvmw package – Abneco Dec 30 '20 at 13:50
it still returns Error: Could not find or load main class demo-0.0.1-SNAPSHOT.jar. The build was successful – Dec 30 '20 at 13:59
once the successful configuration is used you do the following command : java -jar .\target\demo-0.0.1-SNAPSHOT.jar -> the name must match the name of the file defined in the pom.xml name+version – Abneco Dec 30 '20 at 14:05
ok, thank you! I did some stupid mistakes here, thank you for being so patient! – Dec 30 '20 at 14:06

I forgot to tell you that

you can create an order in intellij

Change configuration and launch the command from Intellij by pressing the play button
