Using git commands in a TeamCity Build Step

git teamcity teamcity-7.0

One of my TeamCity v7.0 build projects relies on using a diff between the current development branch and the master branch to determine what needs to be run. I've written a small script that uses something like:

git diff origin/master..origin/QA --name-only --diff-filter=AM | DoSomethingWithThoseFiles

Unfortunately, the build log indicates that git diff is not working. When I go into the buildAgent/work directory for this project, I see that there is no .git folder, so it cannot perform the git operations required.

I've put teamcity.git.use.local.mirrors=true in the buildAgent.properties file as mentioned at TW-15873, but that does not seem to help in any way.

Is there anything I can do to get the list of files changed between two branches in a script for my build step?

Try changing the VCS checkout mode to "Always checkout files on agent" as documented here. That should give the build script access to the .git folder.
