I am working on proof of concept for my project. One of the requirement is to get name of the file latest committed to the main branch. I am calling below command from Azure pipeline.

$a = git diff-tree --no-commit-id --name-only -r $(Build.SourceVersion)

It works fine when I am directly committing file to the main branch. When I create another branch and add file to it and then merge it with main branch and when i try the same command it does not fetch me any value. Alternatively I also tried git diff-tree --no-commit-id --name-only -r HEAD, but this command don't return any value when is file is added to main branch during merge process. Any pointer or help will be appreciated.

You can get the latest commit hash, from the main branch, regardless of whether that's a merge or not using this command:

git log -n 1 --pretty=format:"%H" main

You should then be able to plumb this in to your existing command like:

 git diff-tree --no-commit-id --name-only -r $(git log -n 1 --pretty=format:"%H" main)

P.S. you can restrict it to merges, or non-merges by adding the --merge or --no-merges switches, respectively.
