Github 操作无需提交，工作树干净

Question

我有一个 git 操作，我必须确保没有要添加的内容然后不提交或推送。

但是我如何检查是否有需要添加和提交的内容。

这是我目前的做法的一个例子:

on:
  push:
    branches:
      - testing

name: Build
jobs:
  build:
    name: Build
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
        name: Check out current commit

      - name: Install
        run: npm install

      - name: Build
        run: npm run build

      - name: Commit
        run: |
          git config --local user.email "41898282+github-actions[bot]@users.noreply.github.com"
          git config --local user.name "github-actions[bot]"
          git add .
          git commit -m "Build" -a

      - name: Push
        uses: ad-m/github-push-action@master
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          branch: ${{ github.ref }}

以下是我的建议:

• 您可以添加一个单独的步骤来进行差异检查
• 使用差异检查输出进行添加/提交

它会像下面这样(以下示例是我们如何提取新翻译并 checkin 更改):

      - name: Check if there is any new translations
        id: verify_diff
        run: |
          npx prettier -w packages/trn/transifex
          git diff --quiet packages/trn/transifex/en_US.json || echo "::set-output name=new_translations_exist::true"

      - name: Commit files
        if: steps.verify_diff.outputs.new_translations_exist == 'true'
        run: |
          git config --local user.email "action@github.com"
          git config --local user.name "GitHub Action"
          git add packages/trn/transifex
          git commit -m "bot: extract the latest transactions"
          git push
