【问题描述】：

我在 Azure DevOps 管道中遇到了 PowerShell 任务的新问题。该任务最后一次运行是在 4/27 没有问题，而当前问题发生在下一个版本 5/5。在此期间，没有对管道进行任何更改。

问题似乎源于任务本身，因为它发生在我们的构建和部署管道中的 PowerShell 任务中。其他可能相关的信息，管道在自托管代理上运行并从 Azure DevOps Server 2019 触发。

这是我们正在运行的任务脚本：

Write-Host "##vso[build.addbuildtag]Deploy"

这是 YAML：

steps:

- task: PowerShell@1

  displayName: 'PowerShell Script'

  inputs:

    scriptType: inlineScript

    inlineScript: 'Write-Host "##vso[build.addbuildtag]Deploy" '

    failOnStandardError: false

  continueOnError: true

  condition: and(succeeded(), eq(variables['Build.SourceBranch'], 'refs/heads/master'))

这是产生的错误：

##[debug]Evaluating condition for step: 'PowerShell Script'
##[debug]Evaluating: and(succeeded(), eq(variables['Build.SourceBranch'], 'refs/heads/master'))
##[debug]Evaluating and:
##[debug]..Evaluating succeeded:

【解决方案1】：

尝试以下方法：

另外，添加Add-Type -AssemblyName System.Security

steps:

- task: PowerShell@1

  displayName: 'PowerShell Script'

  inputs:

    scriptType: inlineScript

    inlineScript: |

     Add-Type -AssemblyName System.Security
     
     Write-Host "##vso[build.addbuildtag]Deploy" 

    failOnStandardError: false

  continueOnError: true

  condition: and(succeeded(), eq(variables['Build.SourceBranch'], 'refs/heads/master'))
