How to use the ESLint annotations?

首先查看 issue 中显示的 workflow YAML 和 package.json 脚本，尤其是 eslint:github-action 命令及其输出。检查仓库现有的文档或 action 对 ESLint 注释的行为，然后记录此设置是否应生成拉取请求注释，以及需要哪些配置。

It's my first time using the annotations feature, so please forgive me if this issue is irrelevant.

I'm trying to have annotations in the PR, however all I can get is a simple annotation in the actions screen with irrelevant information. I'm guessing that's a problem of mine, and since there's not a lot documentation (that I could find) about this might as well ask.

That's the output of a failing eslint job. The current configuration is:

  quality:
    needs: [build]

    runs-on: ubuntu-latest

    steps:
      - uses: actions/checkout@v1

      - uses: actions/setup-node@v1
        with:
          node-version: "12.x"

      - name: Cache node modules
        id: cache
        uses: actions/cache@v1
        with:
          path: node_modules # npm cache files are stored in `~/.npm` on Linux/macOS
          key: ${{ runner.os }}-node_modules-${{ hashFiles('**/package-lock.json') }}
          restore-keys: |
            ${{ runner.os }}-build-${{ env.cache-name }}-
            ${{ runner.os }}-build-
            ${{ runner.os }}-

      - name: Install Dependencies
        if: steps.cache.outputs.cache-hit != 'true'
        run: npm ci

      - name: Prettier
        run: npm run fmt:check

      - name: ESlint
        run: npm run eslint:github-action

where my package.json looks like:

  "devDependencies": {
    "@typescript-eslint/eslint-plugin": "^2.12.0",
    "@typescript-eslint/parser": "^2.12.0",
    "eslint": "^6.7.2",
    "eslint-config-prettier": "^6.7.0",
    "prettier": "^1.19.1",
    "serverless-dynamodb-local": "^0.2.38",
    "serverless-offline": "^5.12.1",
    "serverless-plugin-typescript": "^1.1.9",
    "typescript": "^3.7.3"
  },
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1",
    "lint": "eslint functions/**.ts",
    "eslint:github-action": "eslint functions/**",
    "fmt": "prettier --write ./**.{json,js,ts,yml,md}",
    "fmt:check": "prettier --check ./**.{json,js,ts,yml,md}"
  },

I expected that the following error would actually appear in the annotation, and hopefully in the PR too.

 /home/runner/work/utom.is/utom.is/functions/a.ts
  1:0  error  Parsing error: Declaration or statement expected

but as you can get the from screenshot, all I have is that the process completed with error 1.

Is my expectation wrong? Or do I have something misconfigured?

Thanks
