如何在不产生 msbuild.exe 进程的情况下从 Powershell 运行 MSBuild?

问题描述

我正在考虑通过直接点击 MSBuild 程序集从 Powershell 脚本运行 MSBuild(而不是查找 MSBuild 安装路径并将 msbuild.exe 作为子进程启动).

I am considering running MSBuild from a Powershell script by tapping directly to the MSBuild assemblies (as opposed to looking up MSBuild install path and starting msbuild.exe as a child process).

有人做过吗?运行构建的最简单、最直接的方法是什么?您想指出这两种技术是否有任何优点/缺点?(我对在与脚本其余部分相同的进程/appdomain 中运行 msbuild 可能出现的任何问题特别感兴趣).

Has anyone done this? What would be the simplest, most straightforward way to run the build? Are there any pros/cons to either technique you'd like to point out? (I'm especially interested in any issues that might arise from running msbuild in the same process/appdomain as the rest of the script).

目前我的想法是这样的:

Currently my thinking is something along these lines:

[void][System.Reflection.Assembly]::Load('Microsoft.Build.Engine, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a')
[void][Microsoft.Build.BuildEngine.Engine]::GlobalEngine.BuildProjectFile("path/main.proj")

推荐答案

工作并产生输出的最简单的嵌入式构建调用是:

The simplest embedded-build invocation that worked and produced output was:

[void][System.Reflection.Assembly]::Load('Microsoft.Build.Engine, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a')
$engine = New-Object Microsoft.Build.BuildEngine.Engine
$engine.RegisterLogger((New-Object Microsoft.Build.BuildEngine.ConsoleLogger))
$engine.BuildProjectFile('fullPathsome.proj')

然而，事实证明直接在 Powershell (V1) 中嵌入 MSBuild 是有问题的:

However, it turns out embedding MSBuild directly in Powershell (V1) is problematic:

'MSBUILD : warning MSB4056: The MSBuild engine must be called on
a single-threaded-apartment. Current threading model is "MTA".
Proceeding, but some tasks may not function correctly.'

为什么我们仍然在 2009 年在托管环境中工作时缴纳 COM 税?

Why oh why are we still paying COM tax in 2009 while working in a managed environment?

我的结论是在 Powershell (V1) 中嵌入 MSBuild 并不是一个好主意.作为参考，我还包括了我最终使用的基于流程的方法:

My conclusion is that embedding MSBuild in Powershell (V1) is not a good idea. For reference, I'm also including the process-based approach I ended up using:

[void][System.Reflection.Assembly]::Load('Microsoft.Build.Utilities.v3.5, Version=3.5.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a')
$msbuild = [Microsoft.Build.Utilities.ToolLocationHelper]::GetPathToDotNetFrameworkFile("msbuild.exe", "VersionLatest")
&$msbuild fullPathsome.proj
