如何触发构建管道取决于在 Azure DevOps 中创建 PR 请求源分支

Question

I have a Develop branch and Master. My task is to trigger the build pipeline when I create a Pull Request from Develop to Master before merge, depends on Develop branch. The trigger should be from source branch. Can we add tags to trigger the build pipeline based on source branch. I am using classic pipelines and new to ADO. how can I achieve this. Please someone help me to achieve this in detail.

Answer 1

To get a pipeline to trigger when a PR is opened but before it is merged you would need to add a branch policy on master branch to have a build validation step. This will trigger the pipeline to run whenever a PR is opened to master

Build Validation

Answer 2

Unfortunately, PR trigger behaviour varies, depending on which SCM you're using: Azure Repos Git, GitHub, or Bitbucket Cloud. With BB Cloud, the PR build will be triggered when the PR is opened or updated, but not when it is merged. The filter input can be used to specify branches for PR trigger.

Details for each SCM system can be found by clicking on the links on the " Triggers in Azure Pipelines " documentation.
