Azure Devops - Build Automation

Question

I have a Azure DevOps Git Repo with many solutions in it, and are starting down the path of build, test, deploy automation.

I figured out how to run a rebuild if any file changes in the repo.

However, since the repo has many solutions in it, I only want to run a given rebuild of a solution if a specific subfolder changes.

Is that possible, and if so, how do I accomplish this?

Answer 1

you can use path based trigger filters (i'm fairly certain they are only supported in yaml builds). example:

trigger:
  paths:
    include:
      - folder1/*
      - folder2/somefile
      - etc
