Teamcity / Bitbucket - Build a Pull Requests merge commit before merge

Question

I have configured a Bitbucket Server and Teamcity as CI.

Teamcity also builds all commits, which does work very well.

Now I want to build the "Merge commit" which will be generated of a Pull request, before the Pull Request gets merged.

Answer 1

bitbucket creates pull-requests/<pr number>/from branch for every created pull request.

so you can add to vcs root branch specification rule "get only PR branches"

and then add vcs trigger to run it automatically on every new commit in pull-request
