powershell - 从 .ps1 脚本设置环境变量值在 Github Actions 中不起作用

Question

我在 Github Actions 中有两个 ps1 脚本。我的场景:

1. 第一个脚本在构建之前执行
2. 项目构建
3. 第二个脚本在构建后执行。

我需要在第一个脚本中设置值并在第二个脚本中使用它。所以我决定使用 BUILD_NUMBER 环境变量并将其设置为 10 作为默认值。

jobs:
  Droid:
    runs-on: windows-latest
    env:
      BUILD_NUMBER: "10"

在第一个脚本中，我尝试以多种方式设置此变量，但在第二个脚本中，BUILD_NUMBER 的值为 10。

我尝试设置它:

[Environment]::SetEnvironmentVariable($env:BUILD_NUMBER, $buildNumber, 'Machine')

$env:BUILD_NUMBER: '123'

但在第二个脚本中，我通过这个 $newName = "${env:BUILD_NUMBER}" 获得了 10 个值

Github Actions端的全部代码:

name: CI

# Controls when the action will run. Triggers the workflow on push or pull request
# events but only for the master branch
on:
  push:
    branches: 
    - 'master'
    - 'develop'
    - 'feature/*'
    - 'rc/*'
  pull_request:
    branches: 
    - 'master'
    - 'develop'
    - 'feature/*'
    - 'rc/*'


jobs:
  Droid:
    runs-on: windows-latest
    env:
      DOTNET_CLI_TELEMETRY_OPTOUT: 'true'
      BUILD_NUMBER: "10"

    steps:
    - uses: actions/checkout@v1
    - name: Run a calculate version and set sign in password script
      run: .\Scripts\CalculateVersionAndSetSignPassword.ps1
      shell: powershell

# Build goes here. It is skipped by me for testing purposes

    - uses: actions/checkout@v1
    - name: Run a change apk name script
      run: |
       .\Scripts\ChangeApkName.ps1
      shell: powershell

Answer 1

set-env 已被删除 - 请检查 GitHub Actions: Deprecating set-env and add-path commands

作为替代你可以使用

echo "BUILD_NUMBER=yellow" >> $GITHUB_ENV

然后:

jobs:
  show:
    runs-on: ubuntu-latest
    steps:
      - name: Is variable exported?
        run: |
          echo "BUILD_NUMBER=yellow" >> $GITHUB_ENV
      - name: PowerShell script
        # You may pin to the exact commit or the version.
        # uses: Amadevus/pwsh-script@25a636480c7bc678a60bbf4e3e5ac03aca6cf2cd
        uses: Amadevus/pwsh-script@v2.0.0
        continue-on-error: true
        with: 
          # PowerShell script to execute in Actions-hydrated context
          script: | 
            Write-Host $env:BUILD_NUMBER
      - name: Read exported variable
        run: |
          echo "${{ env.BUILD_NUMBER}}"
