Merge Daily Build Branch Task

Use this Azure DevOps custom task to create or update a daily-build branch by merging active pull requests targeting main.

This task uses same script as in PowerShell module

How To Use In YAML Pipelines

1. Install this extension in your Azure DevOps organization.
2. Add the task to a YAML pipeline.
3. Ensure the pipeline has permission to read PRs and push to the target branch.

YAML Example

schedules:
  - cron: '0 3 * * *'
    displayName: 'Daily 3:00 build'
    branches:
      include:
        - main
    always: true

pool:
  vmImage: windows-latest

steps:
  - checkout: self
    persistCredentials: true

  - task: MergeDailyBuildBranch@1
    displayName: Merge active PRs into daily-build
    env:
      DEVOPS_PAT: $(System.AccessToken)
    inputs:
      dailyBuildBranch: daily-build
      mergeStrategy: merge
      defaultPriority: '100'
      skipUnchangedPush: true

Inputs

• dailyBuildBranch: Name of the branch to update (default: daily-build)
• mergeStrategy: merge or squash (default: merge)
• defaultPriority: Fallback priority if no priority:x label is present (default: 100)
• skipUnchangedPush: Skip force-push when branch content is unchanged (default: false)

XML merge driver

The task registers the d365fo-xml git merge driver before merging pull requests. Conflicts caused by different PRs adding, changing or removing order-independent XML elements (table fields, privilege entry points, class methods, ...) are resolved automatically. Enable it in the repository with .gitattributes:

*.xml     merge=d365fo-xml
*.rnrproj merge=d365fo-xml

Optional: commit custom rules as .xmlmergerules in the repository root. Requires PowerShell 7 (pwsh) on the agent.
