GH actions: Get commit message in a PR

get-commit.yml

name: Notify on Pull Request

on:
  pull_request:
    branches: [dev]

jobs:
  send_notification:
    runs-on: ubuntu-latest

    steps:
      - name: Checkout
        uses: actions/checkout@v2
        with:
          fetch-depth: 0
          ref: ${{github.event.after}}
      - name: Get Commit Message
        run: |
          MSG=$(git log --format=%B -n 1 ${{github.event.after}})
          echo "::set-env name=COMMIT_MESSAGE::${MSG}"
      - name: Echo commit message
        run: echo "Commit SHA: ${{github.event.after}}, commit message: ${{env.COMMIT_MESSAGE}} (or ${COMMIT_MESSAGE})"

Just btw you can use
${{ github.event.head_commit.message }}
instead of

@Ismoh github.event.head_commit.message is not exposed in PRs.

Ah yea makes sense. I used it on push. Thanks for pointing out. My bad!

As ::set-env is now deprecated you can fiddle around with envs or define outputs to manage it.

Thanks so much 👍

In case someone landed here for a quick solution. The ${{ github.event.head_commit.message }} is still working fine. FYI.

@neotan no, it doesn't work in PR events as mentioned above (only push). I came here because it doesn't work in PR events.
