Updating NuGet reference in a different repo in Azure DevOps

Question

I have set up a multi-repo in Azure DevOps using Git. Assume I have 2 repos (Repo A and B) for simplicity.

Repo A\'s outcome is a common library DLL. Repo B referenc

Answer 1

Is there a way to add a task in the CD pipeline of Repo A to automatically change the NuGet package reference (to a newer version) in the project of Repo B?

There is no such out-of-the-box approach to doing this.

The simple way is:

Add a Pre-build event to the project in the Repo B with following command line:

nuget.exe update $(ProjectDir)packages.config

In case, when Repo B gets pulled on the local repository, the reference would be updated when you build the project in the repo B. But the limitation for this way is that this method will only modify our local files and will not directly modify the files in the repo. We still need to submit the changes to the repo manually.

The Complex way is:

Add a command line task in the CD pipeline of Repo A to use git command line to clone repo B:

git config --global user.email "xxx@xyz.com"
git config --global user.name "Admin"

git clone  

Then add powershell or any other task to update the Reference, HintPath info in the project file and the package version in the packages.config file.

After modifying the files, add another command line task to submit the changes to the repo:

git commit -m "Update package version"

git push -u origin master

Update:

When you use git clone to clone the repo, you need to provide your certificate in your source link, usually using PAT:

The link looks like:

https://@dev.azure.com//MyTestProject/_git/TestSample

Then we need to replace the first OrganizationName with PAT. So, it will be:

https://@dev.azure.com//MyTestProject/_git/TestSample

For your case, it should be:

https://@xxxxx.Visualstudio.com/....

Then I could clone it successfully.

Hope this helps.
