Heroku - git repository branches destination

Question

I create java app on heroku but I am a little bit confused about branches destination. I have master and HEAD branches. Which should be used for deployment? Can i delete HEAD and have only master?

Answer 1

HEAD is a reference to the checked out commit and master is the usual name for your "default" branch. To deploy to heroku you have to deploy to Heroku's master branch, no matter from where:

Assuming a remote called heroku pointing to Heroku's git:

git push heroku master
git push heroku other_ref:master

The first line pushes your master, to heroku's master. You can specify a different branch like in the second line.
