How to reset build number for a new minor version

[Motty Cohen]

Hi,

I'm using semantic versioning in the format of [major].[minor].[build_number] when building artifacts using bitbucket pipeline.

When moving from one minor version to another (e.g. from 1.0.xx to 1.1.xx), I would like to reset the build number to start again from 0.

Unfortunately, there is no way to reset build number - any ideas how to achieve my goal with bitbucket pipeline?

Hello @Motty Cohen and welcome to the community!

A workaround I can think of is to create a custom repository variable to track the build number value.

For example, you could create a repo variable (Repository Settings > Repository Variables) named $MY_BUILD_NUMBER that starts with the value 0.

For each build where you are not changing the minor version, you can use the value from that variable to create your version [major].[minor].[$MY_BUILD_NUMBER], and then from within the same build you can update the value of the repo variable $MY_BUILD_NUMBER to +1 by making a call to the endpoint  Update a variable for a repository. Subsequent builds will get the updated value of the MY_BUILD_NUMBER.

curl -X PUT -u BBUSERNAME:BB_APPPASSWORD https://api.bitbucket.org/2.0/repositories/WORKSPACE/REPOSITORY/pipelines_config/variables/<VARIABLE UUID>

In the case of a build where the minor version changes, you can set the value of MY_BUILD_NUMBER to 0 again using the same API, and apply the same logic described above.

Hope that helps! Let me know in case you have any questions.

Thank you, @Motty Cohen !
