Answer 1

I revised my application and i had imported wrong maven lib. To schedule a job It is necessary import microprofile scheduling maven artifact:

<dependency>
    <groupId>io.helidon.microprofile.scheduling</groupId>
    <artifactId>helidon-microprofile-scheduling</artifactId>
    <version>3.0.2</version>
</dependency>

import java.util.HashSet;
import java.util.Set;

@ApplicationScoped
public class CustomApplication extends Application {
    @Override
    public Set<Class<?>> getClasses() {
        Set<Class<?>> classes = new HashSet<Class<?>>();
        classes.add(FileService.class);
        return classes;
    }

}

import io.helidon.microprofile.scheduling.Scheduled;
import jakarta.enterprise.context.ApplicationScoped;


/**
 * File service.
 */

@ApplicationScoped
public class FileService {

    @Scheduled("0/2 * * * * ? *")
    //@FixedRate(1)
    public void schedulerFeature()  {
        System.out.println("Running");
    }

}
