通过powershell执行时，msbuild日志不起作用答案

【问题标题】：Msbuild log doesn't work when executed through powershell通过powershell执行时，msbuild日志不起作用

当我使用批处理文件调用 msbuild.exe 时，日志功能可以正常工作。

但是当它用 powershell 编写时，它不会记录任何内容。

以下是我正在使用的 powershell 脚本。知道如何解决这个问题吗？

# Script to invoke build
. ./vsvars32.ps1

Remove-Item "ViewBuild1.log"

$MsbuildBinPath="C:\Windows\Microsoft.NET\Framework\v4.0.30319"


$errorLogFileName="ViewBuild1Errors.log"
$buildLogFileName="ViewBuild1.log"

$MSBuildLogger="/flp1:Append;LogFile=ViewBuild1.log;Verbosity=Normal; /flp2:LogFile=ViewBuild1Errors.log;Verbosity=Normal;errorsonly"

$MSBuildFile="Build.Targets"

Write-Host --------------------------------------------
Write-Host Prepare for the build
Write-Host --------------------------------------------
&"$MsbuildBinPath\Msbuild.exe" $MSBuildFile "/t:Prepare"  "$MSBuildLogger"
if ($LastExitCode -ne 0) {
Write-Host "It failed, send a mail"
} 
#$LastExitCode

&"$MsbuildBinPath\Msbuild.exe" $MSBuildFile "/t:BuildAll"  "$MSBuildLogger"

虽然我在文件记录器中使用了附加选项，但 Viewbuild1.log 在执行后根本没有内容。

【解决方案1】：

$MSBuildLogger 的所有内容都作为单个参数传递给 MSBuild，例如：

PS> $MSBuildLogger="/flp1:Append;LogFile=ViewBuild1.log;Verbosity=Normal; /flp2:LogFile=ViewBuild1Errors.log;Verbosity=
Normal;errorsonly"
PS> echoargs $MSBuildLogger
Arg 0 is </flp1:Append;LogFile=ViewBuild1.log;Verbosity=Normal; /flp2:LogFile=ViewBuild1Errors.log;Verbosity=Normal;erro
rsonly>

尝试使用两个变量：

PS> $MSBuildLogger1="/flp1:Append;LogFile=ViewBuild1.log;Verbosity=Normal;"
PS> $MSBuildLogger2="/flp2:LogFile=ViewBuild1Errors.log;Verbosity=Normal;errorsonly"
PS> echoargs $MSBuildLogger1 $MSBuildLogger2
Arg 0 is </flp1:Append;LogFile=ViewBuild1.log;Verbosity=Normal;>
Arg 1 is </flp2:LogFile=ViewBuild1Errors.log;Verbosity=Normal;errorsonly>

仅供参考，echoargs.exe 是来自 PowerShell Community Extensions 的实用程序。

将整个 MSBuild 命令连接为 powershell var，然后使用 Invoke-Command 执行它。我这样做了，效果很好！

$console_logging_switch = " /clp:Summary"";""Verbosity=$consoleLogLevel"
$file_logging_switch = " /flp:Summary"";""Append"";""LogFile=build.$config.log"";""verbosity=normal"
$file_errlog_switch = " /flp1:Append"";""LogFile=build.$config.err"";""errorsonly"
$file_wrnlog_switch = " /flp2:Append"";""LogFile=build.$config.wrn"";""warningsonly"
$logging_switch = $console_logging_switch + $file_logging_switch + $file_errlog_switch + $file_wrnlog_switch
$targets_switch = " /t:$targets"
$outdir_switch = " /p:OutDir=""$outdir"""
$config_switch = " /p:Configuration=""$config"""

if($skipCodeAnalysis){ $config_switch = " $config_switch /p:RunCodeAnalysis=false " }
if($buildReferences){ $config_switch = " $config_switch /p:BuildProjectReferences=false " }
if($filter -ne $null){ $config_switch = " $config_switch /p:ProjectFilter=$filter " }
$options = $outdir_switch + $config_switch + $logging_switch + $targets_switch

$cmd = "msbuild $project $options"
Invoke-Expression $cmd
