MSbuild不会扩展环境变量 [英] MSbuild doesn't expand environment variables

问题描述

我正在使用MSBuild从命令行构建解决方案文件.在其中，vcxproj文件的路径由环境变量FOO由％FOO％\ ProjName.vcxproj

I'm using MSBuild to build a solution file from the command line. In it, the path to the vcxproj file is specified by an environment variable FOO by %FOO%\ProjName.vcxproj

当我在IDE中打开sln时，便找到并加载了项目.当我从命令行(在同一台计算机上)使用msbuild时，出现以下错误:

When I open the sln in the IDE, I the project is found and loaded. When I use msbuild from the command line (on the same machine) I get an error of:

The Project File "C:\Blah\Blah\%FOO%\ProjName.vcxproj" was not found,

在同一命令提示符下

echo %FOO%  

为我提供正确扩展的路径.

Gives me the correctly expanded path.

推荐答案

来自评论；这是一个已知的错误，来自MS.我最终编写了一个批处理文件来复制sln文件，并扩展环境变量，进行构建并删除新的sln.工作正常.

From the comments; this is a known bug and a wontfix from MS. I ended up writing a batch file to copy the sln file and expand the environment variables, build that, and delete the new sln. Works fine.
