NX monorepo fatal：没有这样的参考：'main~1'

Question

我正在尝试在启用 nx 云的 github actions 中构建我的 nx 应用程序。我总是收到fatal: No such ref: 'main~1'错误。

该命令nx affected --target=build --base=main~1 --head=HEAD --parallel --with-deps在我提交之前有效，但在我提交之后，该命令在本地或 ci 中不再有效。

根据文档，将基础设置为main~1应该仅将其与主分支的先前提交进行比较。

Github Actions 中的完整错误：

yarn run v1.22.10
$ nx affected --target=build --base=main~1 --head=HEAD --parallel --with-deps
fatal: Not a valid object name main~1
fatal: No such ref: 'main~1'
nx affected

Run task for affected projects

untracked changes):

好吧……我终于明白是怎么回事了。登录github actions后git show-ref发现，actions/checkoutaction默认只检查一次commit。

对于触发工作流的 ref/SHA，默认情况下仅获取单个提交。

在指定fetch-depth: 0来获取所有分支的所有引用后，它起作用了。Nx 能够正确比较不同分支和同一分支中先前提交之间的差异。

jobs:
  deploy-updated-apps:
    name: Deploy Updated Apps
    runs-on: ubuntu-latest
    env:
      NX_BRANCH: ${{ github.event.number }}
      NX_RUN_GROUP: ${{ github.run_id }}
    steps:
      - uses: actions/checkout@v2
        with:
          fetch-depth: 0
      - name: Install dependencies
        run: yarn install
      - name: Build affected apps
        run: yarn affected:build:branch

{
  "scripts": {
    "affected:build:branch": "nx affected:build --base=origin/main --head=HEAD --with-deps",
    "affected:build:main": "nx affected:build --base=origin/main~1 --head=HEAD --with-deps",
  },
}
