@Scanned
public class ReleaseNoteTask implements DeploymentTaskType {

    private static final String BAMBOO_URL = "https://bamboo.url"; // URL to bamboo

    @Override

        long versionId = taskContext.getDeploymentContext().getDeploymentVersion().getId();

        // You can use a library like jsoup to read HTML from releaseNotesPath and parse each commit message

        buildLogger.addBuildLogEntry("Release notes: " + releaseNotesPath);
