The Issue
In Azure DevOps Pipelines there is a feature to dynamically configure the build number e.g. at the top of a YAML build add the following to get a version in the form 1.2.25123.1
name: $(major).$(minor).$(year:YY)$(dayofyear).$(rev:r)
Major
&Minor
are user created and managed variablesYear
,Dayofyear
andRev
are built in Azure DevOps pre-defined variables. The first two are obviously based on the current date, therev
is the number of times a pipeline has been run on the current date.
The problem is that there is no equivalent feature to name
in GitHub Actions as build names/numbers are not really a thing in Actions.
However, there are use cases where you want to use some or part of this dynamic build number for other purposes such as version stamping a file.
The Solution
The date related parts of the build number are easy to recreate with PowerShell get-date
,
The revision takes a bit more work, but can be done with more PowerShell and the GitHub CLI.
