如果你想编译一个Delphi项目，请在使用msbuild+Delphi2009时查看“ERROR MSB4040 There is no target in the project”

正确答案是:“有一个批处理文件称为rsvars.bat(在RAD Studio文件夹中搜索它)。在调用MSBuild之前调用它，它将设置必要的环境变量。如果编译器的位置与默认位置不同，请确保rsvars.bat中的文件夹是正确的。”

这个bat不仅会将PATH环境变量更新到正确的。net文件夹，并使用正确的MSBuild.exe版本，还会注册其他必要的变量。

翻了翻登记表，看起来

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\2.0
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\3.5
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0

也许是你想要的;打开regedit.exe，看一看。

通过命令行查询(由Nikolay Botev提供)

reg.exe query "HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\4.0" /v MSBuildToolsPath

通过PowerShell查询(每个MovGP0)

dir HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\

这适用于Visual Studio 2015和2017:

function Get-MSBuild-Path {

    $vs14key = "HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\14.0"
    $vs15key = "HKLM:\SOFTWARE\wow6432node\Microsoft\VisualStudio\SxS\VS7"

    $msbuildPath = ""

    if (Test-Path $vs14key) {
        $key = Get-ItemProperty $vs14key
        $subkey = $key.MSBuildToolsPath
        if ($subkey) {
            $msbuildPath = Join-Path $subkey "msbuild.exe"
        }
    }

    if (Test-Path $vs15key) {
        $key = Get-ItemProperty $vs15key
        $subkey = $key."15.0"
        if ($subkey) {
            $msbuildPath = Join-Path $subkey "MSBuild\15.0\bin\amd64\msbuild.exe"
        }
    }

    return $msbuildPath

}

对于Visual Studio 2017，在不知道确切版本的情况下，你可以在批处理脚本中使用:

FOR /F "tokens=* USEBACKQ" %%F IN (`where /r "%PROGRAMFILES(x86)%\Microsoft Visual 
Studio\2017" msbuild.exe ^| findstr /v /i "amd64"`) DO (SET msbuildpath=%%F)

findstr命令将忽略某些msbuild可执行文件(在本例中为amd64)。

获取最新版本的MsBuild。 最好的方法，对于所有类型的msbuild安装，不同的处理器架构(Power Shell):

function Get-MsBuild-Path
{
    $msbuildPathes = $null
    $ptrSize = [System.IntPtr]::Size
    switch ($ptrSize) {
        4 {
            $msbuildPathes =
            @(Resolve-Path "${Env:ProgramFiles(x86)}\Microsoft Visual Studio\*\*\MSBuild\*\Bin\msbuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:ProgramFiles(x86)}\MSBuild\*\Bin\MSBuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:windir}\Microsoft.NET\Framework\*\MSBuild.exe" -ErrorAction SilentlyContinue)
        }
        8 {
            $msbuildPathes =
            @(Resolve-Path "${Env:ProgramFiles(x86)}\Microsoft Visual Studio\*\*\MSBuild\*\Bin\amd64\msbuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:ProgramFiles(x86)}\MSBuild\*\Bin\amd64\MSBuild.exe" -ErrorAction SilentlyContinue) +
            @(Resolve-Path "${Env:windir}\Microsoft.NET\Framework64\*\MSBuild.exe" -ErrorAction SilentlyContinue)
        }
        default {
            throw ($msgs.error_unknown_pointersize -f $ptrSize)
        }
    }

    $latestMSBuildPath = $null
    $latestVersion = $null
    foreach ($msbuildFile in $msbuildPathes)
    {
        $msbuildPath = $msbuildFile.Path
        $versionOutput = & $msbuildPath -version
        $fileVersion = (New-Object System.Version($versionOutput[$versionOutput.Length - 1]))
        if (!$latestVersion -or $latestVersion -lt $fileVersion)
        {
            $latestVersion = $fileVersion
            $latestMSBuildPath = $msbuildPath
        }
    }

    Write-Host "MSBuild version detected: $latestVersion" -Foreground Yellow
    Write-Host "MSBuild path: $latestMSBuildPath" -Foreground Yellow

    return $latestMSBuildPath;
}

在没有其他工具的情况下，从注册表中批量检索msbuild 15 (Visual Studio 2017)的路径:

set regKey=HKLM\SOFTWARE\WOW6432Node\Microsoft\VisualStudio\SxS\VS7
set regValue=15.0
for /f "skip=2 tokens=3,*" %%A in ('reg.exe query %regKey% /v %regValue% 2^>nul') do (
    set vs17path=%%A %%B
)
set msbuild15path = %vs17path%\MSBuild\15.0\Bin\MSBuild.exe

更好的可用工具:

vswhere:定位Visual Studio 2017和更新的安装，参见get msbuild15 path with batch(使用硬编码路径，如上面的代码片段)。 使用Microsoft.VisualStudio.Workload.MSBuildTools安装VisualStudio PowerShell模块
