Is it possible to only sync on a push to the default branch?

[boudewijn-zicht]

In our workflow we use release branches, so we can work concurrently in branches release/1.0.x and release/1.1.x. However, I only want to run the sync workflow when default branch is pushed.

So when release/1.1.x is the default branch a push to the release/1.0.x should not start the sync workflow.

From what I found it is not possible from github itself, but perhaps this can be tested within the repo-file-sync-action itself?

name: Sync interproject files

on:
  push:
    branches:
      - release/*
  workflow_dispatch:

jobs:
  sync:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: BetaHuhn/repo-file-sync-action@v1
        with:
          GH_PAT: ${{ secrets.REPO_SYNC_PERSONAL_ACCESS_TOKEN }}
          ASSIGNEES: boudewijn-zicht

During the action execution you have access to the default branch under github.event.repository.default_branch. You could add a check so the sync job only gets executed if the ref matches that value:

name: Sync interproject files

on:
  push:
    branches:
      - release/*
  workflow_dispatch:

jobs:
  sync:
    if: github.ref == format('refs/heads/{0}', github.event.repository.default_branch)
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - uses: BetaHuhn/repo-file-sync-action@v1
        with:
          GH_PAT: ${{ secrets.REPO_SYNC_PERSONAL_ACCESS_TOKEN }}

See related StackOverflow thread.

Hope this helps!

This works perfectly, thank you very much!
