在 yaml 代码中出现 Invalid argument 和 MissingMandatoryParameter 错误

Question

在下面的任务中，我在运行 yaml 代码时可能会出现错误，如下所示，

我的yaml代码：

- task: PowerShell@2
  displayName: Clean some space
  inputs:
    targetType: inline
    script: "Write-Host \"Hello World\"\n\nWrite-Host \"Number of files\"\n(Get-ChildItem . -Recurse -ErrorAction SilentlyContinue | Measure-Object).Count\nWrite-Host \"Size\"\n(Get-ChildItem . -Recurse -ErrorAction SilentlyContinue | Measure-Object -Property Length -Sum).Sum / 1Gb\n\n$fol1 = Join-Path $(System.DefaultWorkingDirectory)/bapiweb-PowerBI\"tests\"\n$fol2 = Join-Path $(System.DefaultWorkingDirectory)/bapiweb-PowerBI\"VisualRegressionTesting\"\n$fol3 = Join-Path $(System.DefaultWorkingDirectory)/bapiweb-PowerBI\"buildArtifacts\"\n$fol4 = Join-Path $(System.DefaultWorkingDirectory) \"code\\powerbi\\bapiweb-PowerBI\"\n$fol5 = Join-Path $(System.DefaultWorkingDirectory) \"bapiweb-PowerBI\\BAPIShared\\Services\"\n\nWrite-Host \"Deleting folder \" $fol1 \nRemove-Item -Path $fol1 -Recurse -Force\nWrite-Host \"Deleting folder \" $fol2 \nRemove-Item -Path $fol2 -Recurse -Force\nWrite-Host \"Deleting folder \" $fol3 \nRemove-Item -Path $fol3 -Recurse -Force\nWrite-Host \"Deleting folder \" $fol4 \nRemove-Item -Path $fol4 -Recurse -Force\nWrite-Host \"Deleting folder \" $fol5\nRemove-Item -Path $fol5 -Recurse -Force\n\nWrite-Host \"Number of files\"\n(Get-ChildItem . -Recurse -ErrorAction SilentlyContinue | Measure-Object).Count\nWrite-Host \"Size\"\n(Get-ChildItem . -Recurse -ErrorAction SilentlyContinue | Measure-Object -Property Length -Sum).Sum / 1Gb\n\nWrite-Host \"Bye world\""

我遇到的错误

Join-Path : Cannot process command because of one or more missing mandatory 
parameters: ChildPath.
At C:\__w\_temp\374b657d-7929-4065-b02f-c4ca812bded5.ps1:11 char:9
+ $fol1 = Join-Path C:\__w\1\s/bapiweb-PowerBI"tests"
+         ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    + CategoryInfo          : InvalidArgument: (:) [Join-Path], ParentContains 
   ErrorRecordException
    + FullyQualifiedErrorId : MissingMandatoryParameter,Microsoft.PowerShell.C 
   ommands.JoinPathCommand
 
##[error]PowerShell exited with code '1'.

当我打印测试路径的位置时，我可以看到如下所示以及我在 yaml 代码中更新的内容。

C:\__w\1\s\bapiweb-PowerBI\tests

我尝试了很多方法，但还是坚持这个。请帮我解封。

您缺少 3 个空格：

• 在

  $fol1 = Join-Path $(System.DefaultWorkingDirectory)/bapiweb-PowerBI\"tests\"

• 在

  $fol2 = Join-Path $(System.DefaultWorkingDirectory)/bapiweb-PowerBI\"VisualRegressionTesting\"

• 在

  $fol3 = Join-Path $(System.DefaultWorkingDirectory)/bapiweb-PowerBI\"buildArtifacts\"
