GitHub Actions

# File: .github/workflows/repo-sync.yml

on:
  schedule:
  - cron:  "*/15 * * * *"
  workflow_dispatch:

jobs:
  repo-sync:
    runs-on: ubuntu-latest
    steps:
    - uses: actions/checkout@v4
      with:
        persist-credentials: false
    - name: repo-sync
      uses: repo-sync/github-sync@v2
      with:
        source_repo: ""
        source_branch: ""
        destination_branch: ""
        sync_tags: ""
        github_token: ${{ secrets.PAT }}

If source_repo is private or with another provider, either (1) use an authenticated HTTPS repo clone url like https://${access_token}@github.com/owner/repository.git or (2) set a SSH_PRIVATE_KEY secret environment variable and use the SSH clone url

Workflow overwriting

If destination_branch and the branch where you will create this workflow will be the same, The workflow (and all files) will be overwritten by source_branch files. A potential solution is: Create a new branch with the actions file and make it the default branch. You can update sync_tags to match tags you want to sync, e.g android-14.0.0_*.

Advanced Usage: Sync all branches

Make a backup
Create a new branch in your repo (destination repo), it should not share the name with any branch in source repo
Make the new branch the default branch under repo settings
Use * for both source_branch and destination_branch

Optionally, you can force sync all tags:

with:
  sync_tags: "true" # or * to match all tags.

This will force sync ALL branches to match source repo. Branches that are created only in the destination repo will not be affected but all the other branches will be hard reset to match source repo. ⚠️ This does mean if upstream ever creates a branch that shares the name, your changes will be gone.
