Question
Hi, How do I connect to the event bus in the plugin? I am writing a plugin and I want to listen to all events in nexus. To begin with, I wrote a very simple class:

import com.google.common.eventbus.AllowConcurrentEvents;
import com.google.common.eventbus.Subscribe;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.sonatype.nexus.common.event.Event;
import org.sonatype.nexus.common.event.EventAware;
import org.sonatype.nexus.common.event.EventManager;
import javax.annotation.Nonnull;
import javax.inject.Inject;
import javax.inject.Named;
import javax.inject.Singleton;

@Named
@Singleton
public class AgentHandler implements EventAware {
    private static final Logger LOG = LoggerFactory.getLogger(AgentHandler.class);
    private EventManager eventManager;

    @Inject
    public AgentHandler(final @Nonnull EventManager eventManager) {
        this.eventManager = checkNotNull(eventManager);
        eventManager.register(this);

        LOG.info("Register handler?");
    }

    @AllowConcurrentEvents
    @Subscribe
    public void onNewEvent(final Event event) {
        LOG.info("NEW Event");
    }
}

I could not find information about the reason why it does not receive events. I build the bundle and copy it to the nexus/deploy folder and restart the nexus. After that, I see in the logs that the plugin is loaded, but it does not catch new events
