使用PowerShell x86進行TFS構建以運行

Question

我目前有一個構建定義設置，我在其中調用PowerShell腳本來做一些“額外的工作”，例如使用自定義版本號和DLL簽名。 我遇到的一個問題是，在PowerShell腳本中，我試圖加載程序集，以便可以創建某種類型的對象，並且在嘗試加載程序集時出現錯誤。 我發現需要加載的程序集要求腳本作為x86進程運行。

當我將PowerShell腳本作為Windows Powershell x86而不是常規Windows PowerShell進程運行時，我發現了這一點。 我的構建定義中是否有一種方法可以聲明可以作為哪個進程運行？ 例如構建過程模板，甚至在腳本本身中？

我過去做過一次，所以請親自看看它是否仍在工作。

# Get the path where powershell resides.  If the caller passes -use32 then  
# make sure we are returning back a 32 bit version of powershell regardless 
# of the current machine architecture 
function Get-PowerShellPath() { 
    param ( [switch]$use32=$false, 
            [string]$version="1.0" ) 

    if ( $use32 -and (test-win64machine) ) { 
        return (join-path $env:windir "syswow64\WindowsPowerShell\v$version\powershell.exe") 
    } 

    return (join-path $env:windir "System32\WindowsPowerShell\v$version\powershell.exe") 
} 


# Is this a Win64 machine regardless of whether or not we are currently  
# running in a 64 bit mode  
function Test-Win64Machine() { 
    return test-path (join-path $env:WinDir "SysWow64")  
} 

# Is this a Wow64 powershell host 
function Test-Wow64() { 
    return (Test-Win32) -and (test-path env:\PROCESSOR_ARCHITEW6432) 
} 

# Is this a 64 bit process 
function Test-Win64() { 
    return [IntPtr]::size -eq 8 
} 

# Is this a 32 bit process 
function Test-Win32() { 
    return [IntPtr]::size -eq 4 
} 

function Get-ProgramFiles32() { 
    if (Test-Win64 ) { 
        return ${env:ProgramFiles(x86)} 
    } 

    return $env:ProgramFiles 
} 

function Exec-Script32
{
    param(
        [string] $scriptPath
    )

    $scriptName = Split-Path -Leaf $scriptPath
    $innerLogFilename = Join-Path $env:TEMP $scriptName
    $innerLogFilename += ".log"
    $dataFilename = Join-Path $env:TEMP $scriptName
    $dataFilename += ".data"
    Export-Clixml -Path $dataFilename -InputObject $Args
    $ps32 = Get-PowershellPath -use32
    Write-Verbose "### Re-entering '$scriptPath' in 32-bit shell"
    Write-Verbose "### Logging to '$innerLogFilename'"
    # call this exact file
    & $ps32 -File $scriptPath $dataFilename 2>&1 > $innerLogFilename
    $succeeded = $?
    Write-Output (Get-Content $innerLogFilename)
    Remove-Item $innerLogFilename
    if (!$succeeded) {
        #forward
        throw "$scriptPath failed"
    }
}

為什么不從MSBuild啟動x86版本的PowerShell？

<Exec Command="$(WinDir)\SysWOW64\WindowsPowerShell\v1.0\powershell.exe myscript.ps1"/>

如果您使用的是TeamBuild的工作流變體，只需從SysWOW64路徑中啟動PowerShell.exe。
