MegaLinter中YAML Linter无法检测Git仓库文件问题求助

在CI工作流中使用MegaLinter GitHub Action对包含YAML在内的多类文件做代码检查，YAML Linter已正常启动，但无法检测Git仓库中的文件。MegaLinter输出显示无法列出git忽略文件，最终仅保留0个文件。

工作流代码片段 #

name: Run CI Light Linters
on:
  push:
    branches:
      - main

jobs:
  lint:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout code
        uses: actions/checkout@v2

      - name: Run CI Light Linters
        id: Mega-Linters
        if: ${{ inputs.ENABLE_LINTERS == '' }}
        uses: oxsecurity/megalinter/flavors/ci_light@fda6ac3a38be0e969820709ac16e442464e5a035
        with:
          # other configuration options...
          ENABLE_LINTERS: "YAML_PRETTIER"
        env:
          VALIDATE_ALL_CODEBASE: true
          continue-on-error: true

MegaLinter输出信息 #

MegaLinter now collects the files to analyse (expand for details)

• 修复Checkout步骤的Git仓库拉取
  actions/checkout@v2默认只拉取最新提交，缺少Git仓库元数据，导致MegaLinter无法识别仓库。需添加fetch-depth: 0参数拉取完整仓库信息：

  - name: Checkout code
    uses: actions/checkout@v2
    with:
      fetch-depth: 0
  

• 修正条件判断逻辑
  当前if: ${{ inputs.ENABLE_LINTERS == '' }}的条件在push触发场景下不成立（inputs未定义），会导致MegaLinter执行异常。如果不需要该条件，直接删除；若需保留，需确保ENABLE_LINTERS输入参数的取值符合预期。

• 补充仓库根目录配置
  可通过环境变量明确指定Git仓库根目录，避免路径识别问题：

  env:
    VALIDATE_ALL_CODEBASE: true
    continue-on-error: true
    GIT_REPOSITORY_ROOT: /github/workspace
