How can I pass arguments to a .exe file?

[nicobonder]

I have to create an app with Spring Boot, Picocli and GraalVM. The idea is that the customer be able to execute a .exe file and write some commands to see the information needed. I created a very simple app to see if it was possible, but even this simple app is not working.

In this simple example, the idea is that in the cmd I should be able to do newSimpleCli.exe Nico and it should show: Hola, Nico!!! but as I said, it is not showing that.

If I do:

java -jar newSimpleCli-1.0-SNAPSHOT.jar Nico
It shows the message.

Why is not working with the .exe and how can I solve it?

I have App.java:

@SpringBootApplication
public class App implements CommandLineRunner {

  @Autowired
  private ApplicationContext context;

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

  @Override
  public void run(String... args) throws Exception {
    HelloCommand command = context.getBean(HelloCommand.class);
    int exitCode = new CommandLine(command).execute(args);
    System.exit(exitCode);
  }
}

HelloCommand:

@Component
@Command(name = "hello", description = "Saluda a una persona por nombre")
public class HelloCommand implements Runnable {

  private static final Log LOGGER = LogFactory.getLog(HelloCommand.class);

  @Parameters(index = "0", description = "El nombre de la persona a saludar")
  private String name;

  @Override
  public void run() {
    String greetingName = (name != null) ? name : "World";
    LOGGER.info("Hola, " + greetingName + "!");
    System.out.println("Hola, " + greetingName + "!!!");
  }
}

MANIFEST.MF:

application.properties:

logging.log-file-name=newSimpleCli

1. I created the jar: java -jar newSimpleCli-1.0-SNAPSHOT.jar Nico
2. Then I create the native-image: mvn -Pnative native:compile
3. Then in the cmd I do: newSimpleCli.exe Nico
   And I see this error message:

Unmatched argument at index 0: 'Nico'
Usage: hello
Saluda a una persona por nombre

I also tried doing: newSimpleCli hello Nico
and other variations, but any attend worked.

Finally I could do it.
I was working with this dependency:

info.picocli
picocli
4.7.6

But I needed to work with:

info.picocli
picocli-codegen
4.7.6
