Automatically update a file when merging a pull request

[Deleted user]

I wanted to know if this was possible. We have a file in our code in which we store our version number. I wanted to find out if it is possible to automatically update the version number in that file when we merge a pull request to a specific branch. I see there are options for automating releases in pipelines, but don't know how I would kick off a script to update that file upon a pull request being merged into our trunk.

Hi Michael, I have thought of doing something like that previously for the Android builds which require the build no to be bumped before uploading on Google Play store.

It involves 2 steps:

1. Bumping the version

2. Committing to the git repo

As to where you would add this script:

You can refer to the bitbucket-pipelines.yml  guide on how to trigger a script on "branches". You can simply add your script that bumps the version and commits to the repo.
