PowerShellによるバッチ処理を学習中です．以下の現象で困っています．

## モジュールの宣言

メインの.ps1に以下のように書いております．

```

    # Import
    Import-Module "$($PSScriptRoot)\Module"
    
```

ModuleフォルダにはModule.psm1を配置し中に以下のような関数を書いています．

### 動いてくれる関数 (英語版SOの見よう見まねです)

```

    # Invoke command specifying command path and arguments.
    Function Invoke-Command ($commandPath, $commandArguments)
    {
      Try {
        $pinfo = New-Object System.Diagnostics.ProcessStartInfo
        $pinfo.FileName = $commandPath
        $pinfo.RedirectStandardError = $true
        $pinfo.RedirectStandardOutput = $true
        $pinfo.UseShellExecute = $false
        $pinfo.Arguments = $commandArguments
        $p = New-Object System.Diagnostics.Process
        $p.StartInfo = $pinfo
        $p.Start() | Out-Null
        $p.WaitForExit()
        [pscustomobject]@{
            StdOut = $p.StandardOutput.ReadToEnd()
            StdErr = $p.StandardError.ReadToEnd()
            ExitCode = $p.ExitCode
        }
      }
      Catch {
         exit
      }
    }
    
```

こんな感じで使っています（あくまで該当箇所の抜粋）

```

    # Saxon path（実行環境により修正する）
    $saxon_path = 'D:\My_Documents/Java/SaxonPE10-6J/saxon-pe-10.6.jar'
    
    # Java path（実行環境により修正する）
    $java_path = 'C:/PROGRA~1/Java/jre1.8.0_261/bin'
    $java_exec = $java_path + '/' + 'java.exe'
    # ...
    # Java command option & Saxon option/parameter
    $java_option = ' -Xmx1024m '
    $java_cmd_option = $java_option + " -jar " + $saxon_path + ' -xsl:' + $xsl_path + ' -it:' + $initial_template + ' -o:' + $out_bind_xml_path + ' PRM_XML_PATH=' + $data_xml_path
    
    Write-Host "Start generating bind xml file from directory:'$data_xml_path' to file:'$out_bind_xml_path'" -ForegroundColor Cyan -BackgroundColor Black;
    
    $start_date_time = Get-Date
    
    $ret = Invoke-Command -commandPath $java_exec -commandArguments $java_cmd_option 
    Write-Host $ret.StdOut
    Write-Host $ret.StdErr
    Write-Host 'XSLT processing return code:' $ret.ExitCode  -ForegroundColor Cyan -BackgroundColor Black
    
```

動作ログ（該当箇所のみ）

```

    Start generating bind xml file from directory:'D:/My_Documents/XML2020/XXXXXX/docs/20211104-xml-php-data/xml-xxxxx-2021-08-yy-zz' to file:'C:/Users/toshi/AppData/Local/Temp/tmp214A.tmp'
    XSLT processing return code: 0
    Processing takes 0 minutes  2 seconds.
    
```

### 動いてくれない関数 (こちらも英語版SOの見よう見まねです)

```

    Function Invoke-Executable {
      # from https://stackoverflow.com/a/24371479/52277
      # Runs the specified executable and captures its exit code, stdout
      # and stderr.

      [CmdletBinding()]
      param(
              [Parameter(Mandatory=$true)]
              [ValidateNotNullOrEmpty()]
              [String]$commandPath,
              [Parameter(Mandatory=$false)]
              [String]$commandArguments,
    #          [Parameter(Mandatory=$false)]
    #          [String]$sVerb,
              [Parameter(Mandatory=$false)]
              [Int]$TimeoutMilliseconds=1800000 #30min
          )
    #     Write-Host $commandPath $commandArguments
      
      # Setting process invocation parameters.
      $oPsi = New-Object -TypeName System.Diagnostics.ProcessStartInfo
      $oPsi.CreateNoWindow = $true
      $oPsi.UseShellExecute = $false
      $oPsi.RedirectStandardOutput = $true
      $oPsi.RedirectStandardError = $true
      $oPsi.FileName = $commandPath
      if (! [String]::IsNullOrEmpty($commandArguments)) {
          $oPsi.Arguments = $commandArguments
      }
    #  if (! [String]::IsNullOrEmpty($sVerb)) {
    #      $oPsi.Verb = $sVerb
    #  }
      
      # Creating process object.
      $oProcess = New-Object -TypeName System.Diagnostics.Process
      $oProcess.StartInfo = $oPsi
    
      # Starting process.
      [Void]$oProcess.Start()
      # Tasks used based on http://www.codeducky.org/process-handling-net/ 
      $outTask = $oProcess.StandardOutput.ReadToEndAsync();
      $errTask = $oProcess.StandardError.ReadToEndAsync();
      $bRet=$oProcess.WaitForExit($TimeoutMilliseconds)
      if (-Not $bRet)
      {
        $oProcess.Kill();
      #  throw [System.TimeoutException] ($commandPath + " was killed due to timeout after " + ($TimeoutMilliseconds/1000) + " sec ") 
      }
      $outText = $outTask.Result;
      $errText = $errTask.Result;
      if (-Not $bRet)
      {
          $errText =$errText + ($commandPath + " was killed due to timeout after " + ($TimeoutMilliseconds/1000) + " sec ") 
      }
      $oResult = New-Object -TypeName PSObject -Property ([Ordered]@{
    #      "commandPath"  = $commandPath;
    #      "Args"     = $cArgs -join " ";
          "ExitCode" = $oProcess.ExitCode;
          "StdOut"   = $outText;
          "StdErr"   = $errText
      })
    
      return $oResult
    }
    
```

この関数はVSCodeのPowerShellで以下のエラーになってしまいます．

```

    Start generating DITA topic path:'C:/Users/toshi/AppData/Local/Temp/e5a353ac-226e-4765-b23d-5d1e2bade516/topic'

    Line |
     129 |  $ret = Invoke-Executable -commandPath $java_exec -commandArguments $j …
         |         ~~~~~~~~~~~~~~~~~
         | The term 'Invoke-Executable' is not recognized as a name of a cmdlet, function, script file, or executable program. Check the spelling of the name, or if a path was included, verify that the path is correct

```

このエラーは以下のような呼び出し記述の中で検出されています．

```

    # Saxon path, Java pathは上記の使いまわしです．
    
    # Java command option & Saxon option/parameter
    $java_option = ' -Xmx1024m '  
    $java_cmd_option = $java_option + " -jar " + $saxon_path + ' -t -xsl:' + $xsl_path + ' -s:' + $out_map_path + ' -o:' + $out_xml_path + ' -ea:on' + ' PRM_BIND_XML_URL=' + $bind_xml_url + ' PRM_OUTPUT_DIR_URL=' + $out_topic_dir_url
    
    Write-Host "Start generating DITA topic path:'$out_topic_dir'" -ForegroundColor Cyan -BackgroundColor Black;
    $start_date_time3 = Get-Date
    
    $ret = Invoke-Executable -commandPath $java_exec -commandArguments $java_cmd_option 
    
    Write-Host $ret.StdOut
    Write-Host $ret.StdErr
    Write-Host 'XSLT processing return code:' $ret.ExitCode  -ForegroundColor Cyan -BackgroundColor Black
    
```

ともかくモジュールも関数も初めて作ったので勝手がわかりません．  
原因わかりましたらご教示ください．

VSCodeのPowerShellのPSVersionTableの情報は以下の通りです．

```

    PS D:\My_Documents\XML2020\XXXXXX\docs\xml-php> $PSVersionTable
    
    Name                           Value

question
powershell
PowerShellのモジュールと関数の作り方：関数が認識されず呼び出せません．
大変失礼いたしました．自己解決しました．  
フォルダに以前のVSCodeの設定（？）が残存していて影響を与えていたようです．".ionide"というフォルダを削除したらなんの問題もなく動いてくれました．
