Git keep file in sync task between 2 repos in Azure DevOps

You can't just do the merge like you did because it's 2 different repositories, also, do you really want to merge the whole repo? you need only one file to sync.

You can make it happen with this logic:

• Clone the second repo
• Copy FileA from repo 1 to repo 2
• Commit & Push

I wrote a small PowerShell script that works:

cd $(Agent.BuildDirectory)
git clone https://[email protected]/{organzition}/{project}/_git/{repo-name}
cd {repo-name}
git checkout branch-name # if the synced file not in master
# Assuming the synced file name is "test.txt" and he exists in the folder "common"
Copy-Item $(Build.SourcesDirectory)\common\test.txt $(Agnet.BuildDirectory)\{repo-name}\common -Force
# If you use Hosted agent you need to configure the email & address
git config --globa user.email "[email protected]" 
git config --global user.name "Azure DevOps Build"
git add common/test.txt
git commit -m "Sync test.txt"
git push

Now create 2 pipelines, in each pipelines do the trigger only the common file you want to sync:

With the above script:
