I am running tfs 2015 and have it build when a pull request is create to a certain branch.
It appears that the retention policies are not working on it as they should be only lasting 1 day and they are there for months at a time.
I think the problem is the source branch. on the pull requests builds it has it as the refs/pull/688/merge. The retention policies look for refs/heads/*.
Is this why they are not getting deleted and if so how can I add the pull request builds to get them deleted?
I have tried typing refs/pull/* in the retention but it comes back as refs/head/refs/pull/*
