There are a few helpful [questions and answers][1] online,
[1]: How to git diff on a Azure CI pipeline, but they seem to be working in a single-repository environment. I’m using one git repository for the project source, another for a department-wide YAML code repo that covers several projects.
My current challenge is getting a list of changed files as a result of a PullRequest, IndividualCI, or BatchCI Build.Reason for the product repo. The list is needed for a CI static code analysis.
Using git diff --name-only HEAD^ HEAD (or HEAD~ HEAD or @~ @) all give me fatal: not a git repository (or any of the parent directories): .git
With two repositories, the Build.SourceDirectory gets the name of the repositories appended, but I haven’t been able to find for to use that information (e.g. agent_work1sfoo) in or before the git diff call.
Has anyone come across that problem, or any suggestions for a solution?
Assuming you have defined additional repository resource(s) in your YAML pipeline to be consumed together with the self repo, and according to the document,
Unless a
pathis specified in thecheckoutstep, source code is placed in a default directory. This directory is different depending on whether you are checking out a single repository or multiple repositories.Multiple repositories: If you have multiple
checkoutsteps in your job, your source code is checked out into directories named after the repositories as a subfolder ofsin(Agent.BuildDirectory). If(Agent.BuildDirectory)isC:agent_work1and your repositories are namedtoolsandcode, your code is checked out toC:agent_work1stoolsandC:agent_work1scode,
Therefore, you may try the sample YAML pipeline below to run git diff in different repo paths on that agent machine.
resources:
repositories:
- repository: RepoA
name: RepoA
type: git
variables:
RepoA.name: $[ resources.repositories.RepoA.name ]
RepoA.ref: $[ resources.repositories.RepoA.ref ]
RepoA.version: $[ resources.repositories.RepoA.version ]
steps:
# Set fetchDepth as 0 to disable the dault shallow fetch 1
- checkout: self
fetchDepth: 0
- checkout: RepoA
fetchDepth: 0
- script: |
echo "================ 1. Show file structure in Pipeline.Workspace ================"

echo "================ 2. Show self repo info and run git diff ================"
cd $(Agent.BuildDirectory)/s/$(Build.Repository.Name)

git diff --name-only $(Build.SourceVersion)^ $(Build.SourceVersion)

cd $(Agent.BuildDirectory)/s/$(RepoA.name)
echo "RepoA name: $(RepoA.name)"

git diff --name-only $(RepoA.version)^ $(RepoA.version)
