Heroku - Error during git push/deployment, The same version of this code has already been built

I have a problem deploying my springboot application to Heroku. After running git push heroku master, I am encountering the error below:

I am clueless into why this error occurred. I have two remote repositories on which I push my code, one from Heroku and one in Github. I have tried the command below based from the answer from this question, Heroku: If you are developing on a branch and deploying via git you must run:

git push heroku master:main

But still the error persists. Is there any command that I could try on the Heroku CLI to solve this problem?

Solution

  • After some few tries, I was thinking that the cause of the problem was maybe an interrupted git push heroku master command, which was then proceeded by a re-execution of the same command, causing the error below:

    remote:  !     Push failed
remote:  !
remote:  ! ## Warning - The same version of this code has already been built:             31199a7acec03a3cb614ebaaf6c7720cee6684bd
remote:  !
remote:  ! We have detected that you have triggered a build from source code with version 31199a7acec03a3cb614ebaaf6c7720cee6684bd
remote:  ! at least twice. One common cause of this behavior is attempting to deploy         code     from a different branch.
remote:  !

    So what I did was, I pushed another commit, then retried the same command git push heroku master, which resulted to a successful deployment.

    Also, shoutout to RainXCat's answer and insights, now I know Heroku does not allow two git repositories on the same directory/folder.
