Build Feature Plugin

Hello,

So, i'm building a new plugin for teamcity as a Build Feature.

Right now I have it being triggered like this. With a listener for the buildFinished.

public BuildStatusListener(@NotNull final EventDispatcher<BuildServerListener> listener,
                           @NotNull final ChangeStatusUpdater updater)
{
    this.updater = updater;
    listener.addListener(new BuildServerAdapter()
    {

        @Override
        public void buildFinished(SRunningBuild build)
        {
            runStuff(build);
        }
    });
}

And inside I basically iterate through the build features to check if my feature is active.

for (SBuildFeatureDescriptor feature : buildType.getResolvedSettings().getBuildFeatures())
{
    if (!feature.getType().equals(myFeature.FEATURE_TYPE))
    {
        continue;
    }

Now, is there a better way to do this? I don't really like this approach. Seems a bit hammered.

I don't want my code to be executed after every single build. Is there a listener or trigger that only applies IF my Build Feature is active?

Thanks,
