请验证文件路径是否存在

Question

我在使用自托管 Windows 代理时遇到以下错误。

Answer 1

##[错误]无法找到可执行文件：'bash'。

问题的原因是 Bash 不是 Windows 机器的内置工具。

为了解决这个问题，我们可以安装 git bash 并在代理机器的环境变量 PATH 中添加 bash 命令文件夹。

如何在下面提到的管道中添加任务或阶段来解决此错误

要将所有步骤集成到 Pipeline 中，您可以添加以下任务：

steps:

- task: PowerShell@2
  displayName: Install Git And Config PATH ENV
  inputs:
    targetType: 'inline'
    script: |
      # Define the URL of the Git installer
      $gitInstallerUrl = "https://github.com/git-for-windows/git/releases/download/v2.40.1.windows.1/Git-2.40.1-64-bit.exe"
      
      # Define the path to save the installer
      $installerPath = "$env:TEMP\Git-2.40.1-64-bit.exe"
      
      # Download the Git installer
      Invoke-WebRequest -Uri $gitInstallerUrl -OutFile $installerPath
      
      # Run the installer silently
      Start-Process -FilePath $installerPath -ArgumentList "/SILENT", "/NORESTART" -Wait
      
      # Optionally, remove the installer after installation
      Remove-Item -Path $installerPath
      $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User")
      echo $env:Path
      $gitpath = git --exec-path
      $bashpath = $gitpath.Replace('mingw64/libexec/git-core','bin')
      echo "##vso[task.setvariable variable=PATH]$bashpath;$(PATH)"


- task: Bash@3
  inputs:
    targetType: 'inline'
    script: |
      echo "test"

在这种情况下，我们可以使用 Windows 自托管代理中的 Bash 任务。

另一方面，从您的 YAML 示例中，您正在使用 bash 任务来设置 Pipeline 变量。

您也可以考虑改为使用PowerShell任务来实现相同的功能。在这种情况下，您不需要在 Pipeline 中配置 bash 环境变量。

例如：

  - powershell: |
      echo "##vso[task.setvariable variable=xxxx-outcome;isOutput=true]$(result)"
    name: outputForDashboard
    condition: always()

更新：

由于 git bash 存在于您的本地计算机上（

C:\Program Files\Git\bin

），您可以添加以下 powershell 任务来设置 env 变量。

steps:


- task: PowerShell@2
  displayName: Install Git And Config PATH ENV
  inputs:
    targetType: 'inline'
    script: |

      $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User")
      echo $env:Path
      $bashpath = "C:\Program Files\Git\bin"
      echo "##vso[task.setvariable variable=PATH]$bashpath;$(PATH)"


- task: Bash@3
  inputs:
    targetType: 'inline'
    script: |
      echo "test"

更新2：

resources:
  pipelines:
  - pipeline: xxx
    source: xxx
    project: xxx
    trigger:
      stages:
      - Deploy_xxx
      xxx

variables:
- name: dashboardFileDirectory
  value: "C:\\Users\\svcAzurexxx\\test-team-xxxfiles"
- name: setJava
  value: "false"

  displayName: xxx
  jobs:
    - job: BuildAndTest
      pool: 
       name: "Test"
      displayName: 'Build and Test'
      steps:
      - task: PowerShell@2
        displayName: Config PATH ENV
        inputs:
          targetType: 'inline'
          script: |

            $env:Path = [System.Environment]::GetEnvironmentVariable("Path","Machine") + ";" + [System.Environment]::GetEnvironmentVariable("Path","User")
            echo $env:Path
            $bashpath = "C:\Program Files\Git\bin"
            echo "##vso[task.setvariable variable=PATH]$bashpath;$(PATH)"

      - bash: |
          echo "##vso[task.setvariable variable= Automation-API-outcome;isOutput=true]$(result)"
        name: outputForDashboard
        condition: always()

    # run the report creation in a new job on microsoft hosted agents
    - job: allureReport
      pool: "Azure Pipelines"
      dependsOn: BuildAndTest
      condition: always()
      steps:
      - template: templates/ Automation.yml
        parameters:
          pipelineArtifactName:  Automation-API
          reportName:  Automation-Test-Report

      displayName: Save details
      variables:
         Automation-API-outcome: $[stageDependencies.Test1.BuildAndTest.outputs['outputForDashboard. Automation-API-outcome']]
      steps:
      - task: PowerShell@2
        inputs:
          targetType: 'inline'
          script: |
            echo "$( Automation-API-outcome)" | Out-File -FilePath $(dashboardFileDirectory)\ Automation-API-outcome
