你也可以把MSBuild.exe的路径打印到命令行:

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

本处地点

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

给出可执行文件的位置。

但如果你需要保存任务扩展的位置，它是打开的

%ProgramFiles%\MSBuild

从MSBuild 2017 (v15)开始，MSBuild现在安装在每个Visual Studio版本下的文件夹中

以下是在我的机器上找到MSBuild.exe的一些例子:

C:\windows\Microsoft.NET\Framework\v2.0.50727\MSBuild.exe  (v2.0.50727.8745  32-bit)
C:\windows\Microsoft.NET\Framework64\v2.0.50727\MSBuild.exe  (v2.0.50727.8745  64-bit)
C:\Windows\Microsoft.NET\Framework\v3.5\MSBuild.exe  (v3.5.30729.8763 32-bit)
C:\Windows\Microsoft.NET\Framework64\v3.5\MSBuild.exe  (v3.5.30729.8763 64-bit)
C:\Windows\Microsoft.NET\Framework\v4.0.30319\MSBuild.exe  (v4.7.2053.0 32-bit)
C:\Windows\Microsoft.NET\Framework64\v4.0.30319\MSBuild.exe  (v4.7.2053.0 64-bit)
C:\Program Files (x86)\MSBuild\12.0\Bin\MSBuild.exe  (v12.0.21005.1 32-bit)
C:\Program Files (x86)\MSBuild\12.0\Bin\amd64\MSBuild.exe (v12.0.21005.1 64-bit)
C:\Program Files (x86)\MSBuild\14.0\Bin\MSBuild.exe  (v14.0.25420.1 32-bit)
C:\Program Files (x86)\MSBuild\14.0\Bin\amd64\MSBuild.exe  (v14.0.25420.1 64-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe  (v15.1.1012+g251a9aec17 32-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\amd64\MSBuild.exe (v15.1.1012+g251a9aec17 64-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\{LicenceName}\MSBuild\Bin\MSBuild.exe (v15.1.1012.6693 32-bit)
C:\Program Files (x86)\Microsoft Visual Studio\2017\{LicenceName}\MSBuild\Bin\amd64\MSBuild.exe (v15.1.1012.6693 64-bit)

这个powershell方法从多个源获取msBuild的路径。按顺序尝试:

首先使用vwhere(因为Visual Studio似乎有更多最新版本的msBuild)。 C:\Program Files (x86)\Microsoft Visual Studio\2017\Professional\MSBuild\15.0\Bin\MSBuild.exe 如果没有发现尝试注册表(框架版本)。 C:\Windows\ Microsoft.NET \ Framework64 \ v4.0.30319 \ msbuild.exe

Powershell代码:

Function GetMsBuildPath {

    Function GetMsBuildPathFromVswhere {
        # Based on https://github.com/microsoft/vswhere/wiki/Find-MSBuild/62adac8eb22431fa91d94e03503d76d48a74939c
        $vswhere = "${env:ProgramFiles(x86)}\Microsoft Visual Studio\Installer\vswhere.exe"
        $path = & $vswhere -latest -prerelease -products * -requires Microsoft.Component.MSBuild -property installationPath
        if ($path) {
            $tool = join-path $path 'MSBuild\Current\Bin\MSBuild.exe'
            if (test-path $tool) {
                return $tool
            }
            $tool = join-path $path 'MSBuild\15.0\Bin\MSBuild.exe'
            if (test-path $tool) {
                return $tool
            }
        }
    }

    Function GetMsBuildPathFromRegistry {
        # Based on Martin Brandl's answer: https://stackoverflow.com/a/57214958/146513
        $msBuildDir = Get-ChildItem 'HKLM:\SOFTWARE\Microsoft\MSBuild\ToolsVersions\' |
            Get-ItemProperty -Name MSBuildToolsPath |
            Sort-Object PSChildName |
            Select-Object -ExpandProperty MSBuildToolsPath -last 1
        $msBuildPath = join-path $msBuildDir 'msbuild.exe'
        if (test-path $msBuildPath) {
            return $msBuildPath
        }
    }

    $msBuildPath = GetMsBuildPathFromVswhere
    if (-Not $msBuildPath) {
        $msBuildPath = GetMsBuildPathFromRegistry
    }
    return $msBuildPath
}

如果你有冒险精神，你也可以在https://github.com/Microsoft/msbuild/releases/上从GitHub获得源代码和MsBuild的最新版本

@AllenSanborn有一个很棒的powershell版本，但有些人要求只使用批处理脚本进行构建。

这是@bono8106回答的应用版本。

msbuildpath.bat

@echo off

reg.exe query "HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\14.0" /v MSBuildToolsPath > nul 2>&1

for /f "skip=2 tokens=2,*" %%A in ('reg.exe query "HKLM\SOFTWARE\Microsoft\MSBuild\ToolsVersions\14.0" /v MSBuildToolsPath') do SET "MSBUILDDIR=%%B"

IF NOT EXIST "%MSBUILDDIR%" goto MissingMSBuildToolsPath
IF NOT EXIST "%MSBUILDDIR%msbuild.exe" goto MissingMSBuildExe

exit /b 0
