为什么即使我使用MSBuild任务也找不到项目文件? [英] Why is the project file not found even though i am using an MSBuild task?

问题描述

我创建了一个Azure Devops Build管道，并试图在bitbucket(git)上构建我的ASP.NET MVC和Angular混合站点项目.

该项目首先被签出，并且nuget恢复了必要的软件包，但是，我无法构建.NET！

我偶然发现了

我还认为x64架构可能与它有关，但这并不能解决问题...

我偶然发现了一些有趣的帖子，例如

  Microsoft Visual Studio解决方案文件，格式版本12.00#Visual Studio版本16VisualStudioVersion = 16.0.29806.167MinimumVisualStudioVersion = 10.0.40219.1Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}")="Bobby.ProjectA"，"Bobby.ProjectA \ Bobby.ProjectA.csproj"，"{12345FE4-4CB9-3245-9A45-DB9A4AF1DFEB}". 

解决方案

基于我的测试，当错误的csproj文件路径映射到 .sln中时，我可以重现类似的问题.文件.

您可以检查您的 .sln文件->项目字段.

例如:

文件结构

.csproj文件位于WebApplication2文件夹下，因此项目相对路径为 WebApplication2 \ WebApplication2.csproj .

.sln文件

  VisualStudioVersion = 16.0.30611.23MinimumVisualStudioVersion = 10.0.40219.1Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}")="WebApplication2"，"WebApplication2 \ WebApplication2.csproj"，"{497AD76F-222C-4BEB-BDCB-401B0E80B5CE}"结束项目 

更新:

与Cataster讨论后，可以通过在Msbuild任务中指定 **/*.csproj 来解决导入项目的问题.

例如:

I created an Azure Devops Build pipeline and i am trying to build my ASP.NET MVC and Angular hybrid site project on bitbucket (git).

The project first gets checked out, and nuget restores the necessary packages, however, i cannot get the .NET to build!

Ive stumbled on this post here that basically advises against using the dotnet build task and recommended just using Visual Studio Build or MSBuild tasks instead.

Nether are working for me though!

• I tried VS2017-win2016 hosted agent, didnt work.
• I tried Windows 2019 hosted agent, didnt work.

I am getting this error:

Bobby.ProjectA\Bobby.ProjectA.csproj(713,3): Error MSB4019: The imported project "C:\Program Files\dotnet\sdk\5.0.100\Microsoft\VisualStudio\v16.0\WebApplications\Microsoft.WebApplication.targets" was not found. Confirm that the expression in the Import declaration "C:\Program Files\dotnet\sdk\5.0.100\Microsoft\VisualStudio\v16.0\WebApplications\Microsoft.WebApplication.targets" is correct, and that the file exists on disk.

Since Ubuntu is faster, i also tried that, however, as expected Visual Studio Build task fails with that since VS is not installed on the machine. So i tried with MSBuild and that worked fine with Ubuntu, however, still getting same error that the project file was not found...

I pretty much exhausted my searches and not sure how to solve this.

Heres some screenshots that show my pipeline tasks:

I also thought maybe x64 architecture would have something to do with it, but that didnt resolve the issue...

Ive stumbled on some other interesting posts like this one, but im not sure what adding the project to source countrol means in the answer given, considering my csproj files are already hosted in the repo and being checked out before any tasks run...

My project structure and .sln path (Project):

Microsoft Visual Studio Solution File, Format Version 12.00
# Visual Studio Version 16
VisualStudioVersion = 16.0.29806.167
MinimumVisualStudioVersion = 10.0.40219.1
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "Bobby.ProjectA", "Bobby.ProjectA\Bobby.ProjectA.csproj", "{12345FE4-4CB9-3245-9A45-DB9A4AF1DFEB}"

解决方案

Based on my test, I could reproduce the similar issue when the wrong csproj file path is mapped in the .sln file.

You could check your .sln file -> project field.

For example:

File structure

The .csproj file is under the WebApplication2 folder, so the project relative path is WebApplication2\WebApplication2.csproj.

.sln file

VisualStudioVersion = 16.0.30611.23
MinimumVisualStudioVersion = 10.0.40219.1
Project("{FAE04EC0-301F-11D3-BF4B-00C04F79EFBC}") = "WebApplication2", "WebApplication2\WebApplication2.csproj", "{497AD76F-222C-4BEB-BDCB-401B0E80B5CE}"
EndProject

Update:

After discussion with Cataster, the import Project issue can be resolved by specifying **/*.csproj in Msbuild task.
