I’m attempting to get the commit message from the merge of the DEV to MAIN branch, so I can insert in the body of the release.

I attempted using get-commits but did not work.

This is the commit message I mean:

This is my YAML file:

name: "Build Android app"

on:
  push:
    branches: ['main', 'dev']

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: 🗂️ Checkout repository
        uses: actions/checkout@v2

      - name: ☕ Instalando Java
        uses: actions/setup-java@v3
        with:
          java-version: 17

          cache: gradle

Yeah, so basically I wanted the commit message from dev to main to be content from the release. I could manage to do that with:

- name: 📝 Pegar mensagem commit do merge
        if: github.ref == 'refs/heads/main'                        
        env:
          GITHUB_TOKEN: ${{ secrets.GH_TOKEN }}
        run: |
            response=$(curl -s -X POST 
              -H "Authorization: bearer $GITHUB_TOKEN" 
              -H "Content-Type: application/json" 
              -d '{"query": "query { repository(owner: "repo", name: "repo-app") { pullRequest(number: ${{ steps.last_pr.outputs.last_pr_number }}) { body } } }"}' 
              https://api.github.com/graphql)

            # Extract the body content using jq and store it in an environment variable
            body_content=$(echo "$response" | jq -r '.data.repository.pullRequest.body')

            echo "PR body content: ${{ steps.last_pr.outputs.last_pr_number }} $body_content"

            # Workaround for multi-line PR body content
            # Use printf with multiline input to preserve newlines
            echo "commit_message<<EOF" >> $GITHUB_ENV
            printf "%sn" "$body_content" >> $GITHUB_ENV
            echo "EOF" >> $GITHUB_ENV

(Edit)

For what you’re trying to achieve, an approach that has worked for me in the past was using the GitHub API to fetch the commits and grabbing the message.

So I’ll update your YAML file to capture the latest commit message after a merge like this:


name: "Build Android app"

on:
  push:
    branches: ['main', 'dev']

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: 🗂️ Checkout repository
        uses: actions/checkout@v2

      - name: ☕ Instalando Java
        uses: actions/setup-java@v3
        with:
          java-version: 17
          distribution: adopt
          cache: gradle

      - name: 🔍 Validando Gradle
        uses: gradle/wrapper-validation-action@v1

      - name: 🖥️ Instalando Node  
        uses: actions/setup-node@v3
        with:
          node-version: '20'
          cache: 'yarn'

      - name: 📦 Instalando dependências
        run: yarn install

      - name: 🩹 Patch dependências
        run: yarn patch-package

      - name: Get commit message from merge
        id: commit_message
        run: |
          COMMIT_MSG=$(git log -1 --pretty=%B)
          echo "commit_message=$COMMIT_MSG" >> $GITHUB_ENV

      - name: Use commit message in release
        run: |
          echo "Creating release with commit message: ${{ env.commit_message }}"

#continue with your config

The new step I added, Get commit message from merge runs a git log command to extract the latest commit message and stores it in a GitHub environment variable (commit_message).

Then the environment variable is made available for other steps(such as creating a release or using it in other parts of your workflow).
