Accessing the extended (multi-line) Git commit message in Azure Pipeline YAML

Question

In AppVeyor we get the extended part of the Git commit message using the APPVEYOR_REPO_COMMIT_MESSAGE_EXTENDED environment variable, but I can't see an equivalent in Azure Pipelines.

If I create a bash step containing printenv | sort to view all the available environment variables in my YAML pipeline then the output indicates that the BUILD_SOURCEVERSIONMESSAGE only contains the first line of the commit message, and no EXTENDED equivalent exists. I can't see anything in the docs either. Our repo is hosted in GitHub rather than in Azure DevOps if this makes a difference.

Is possible to get the extended commit message in an Azure Pipeline?

Answer 1

I've worked out an alternative way to get what I needed. The following line (in powershell) assigns the most recent commit message to $commitMessageFull as an array of strings, one string per line.

$commitMessageFull = git log -1 --pretty=%B

You can then split the first line and the extended message out with this:

$first, $extended = $commitMessageFull

The $first variable now contains a single string which is the first line of the commit message, and $extended contains an array of strings which is the remaining lines.
