Can a Bamboo plugin be notified when a plan is deleted?

[Ed Jackson]

I'm developing a plugin that stores settings per plan in PluginSettings. I'm wondering if there's some sort of callback mechanism whereby my plugin can be notified when a plan is deleted so it can remove its corresponding settings.

I'm fairly new to Bamboo development, so apologies if this obvious. :)

EDIT:

In case another n00b runs across this, here's my working example. Just need to add the appropriate bambooEventListener block in your atlassian-plugin.xml.

package com.example.bamboo.testPlugin

import com.atlassian.bamboo.event.ChainDeletedEvent;
import com.atlassian.bamboo.plan.PlanKey;
import com.atlassian.event.api.EventListener;
import com.atlassian.event.api.EventPublisher;
import com.atlassian.plugin.spring.scanner.annotation.component.Scanned;
import com.atlassian.plugin.spring.scanner.annotation.imports.ComponentImport;
import org.jetbrains.annotations.NotNull;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
import org.springframework.beans.factory.DisposableBean;

import javax.inject.Inject;


@Scanned
public class PlanDeletionListener implements DisposableBean {
    private static final Logger log = LoggerFactory.getLogger(PlanDeletionListener.class);
    @ComponentImport private final EventPublisher eventPublisher;

    @Inject
    public PlanDeletionListener(EventPublisher eventPublisher) {
        log.info("PlanDeletionListener instantiated.");
        this.eventPublisher = eventPublisher;
        eventPublisher.register(this);
    }

    @EventListener
    public void onChainRemoved(@NotNull ChainDeletedEvent chainDeletedEvent) {
        PlanKey key = chainDeletedEvent.getPlanKey();
        String message = ("Plugin received deletion event for plan with key "+key.getKey());
        log.info(message);
    }

    public void destroy() throws Exception {
        eventPublisher.unregister(this);
        log.info("PlanDeletionListener destroyed.");
    }
}

Yes, there's com.atlassian.bamboo.event.ChainDeletedEvent

You can create listener

@EventListener
public void onChainRemoved(@NotNull ChainDeletedEvent chainDeletedEvent)
{
     ....do what you need
}

Thanks, that sent me down the right path.
