You can use Jenkins Batch Task Plugin if you want to deploy the latest revision to Heroku. Our deployment has two steps: a rake task that pushes assets to S3/Cloudfront and a git push. So the batch task attached to our repo looks like this.
git rev-parse HEAD
echo $GIT_COMMIT
bundle exec rake heroku:predeploy
git push git@heroku.com:heroku-app.git $GIT_COMMIT:master
The first two lines are there for logging, so that we know which revision was pushed to Heroku.
We’re now missing two important pieces from Heroku-bartender’s functionality: a visual of which revision has been deployed and the ability to run a task on any previous build.
