Deploy git subdirectory on heroku

Question

I have to deploy a git subdirectory from a non master branch. I have looked at this answer and to the docs on Heroku, but when I issue

git subtree push --prefix visualizations heroku develop:master

I get the following error

error: src refspec d02911f4e410256fae0760f87f186289436ff98b:refs/heads/develop does not match any

And I really don't know how to proceed.

Are you sure that there are commits on the develop branch? – subsub Sep 18 '13 at 11:48 — subsub, Sep 18 '13 at 11:48
Yes, I have done a commit with the updated Procfile. – gcedo Sep 18 '13 at 13:35 — gcedo, Sep 18 '13 at 13:35

The git subtree push command does not use the localBranch:remoteBranch syntax used in the plain git push to define what local branch gets pushed into what remote branch. What you might need is just to change that last parameter:

git subtree push --prefix visualizations heroku master

Since git subtree push creates a new commit for the subtree, and that is the one pushed, there is no need define a local branch as a source.

With the above command you are telling git to create a new subtree commit from visualizations and to push it to the master branch on the heroku remote.
