For my service Service Id is not getting Generated in my project bundle I cannot see it.

Below is the code for my service and its implementation

SimpleService.java :

package com.aem.demo.core;

public interface SimpleService
{
public String MyName();
}

SimpleServiceImpl.java :

package com.aem.demo.core.impl;

import org.apache.felix.scr.annotations.Activate;
import org.apache.felix.scr.annotations.Component;
import org.osgi.service.component.ComponentContext;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.aem.demo.core.SimpleService;

@8220494(metatype = true, label = "Simple Service Info")
public class SimpleServiceImpl implements SimpleService
{
private final Logger logger = LoggerFactory.getLogger(getClass());
@580286
public void activate(ComponentContext cc)
{
logger.info("------ Service Activated -----");
logger.info("\n {}={}", cc.getBundleContext().getBundle().getBundleId(), cc.getBundleContext().getBundle().getSymbolicName());
}

@9944223
public String MyName()
