为什么C:\ Program Files \ dotnet \ sdk \ 3.1.201中缺少msbuild.exe?导致AzureDevOps构建步骤失败

I have a very simple WPF project (.Net 4.7.2) and Unit Test project (MSTest .Net Core) and I'm trying to get it to build in Azure Pipelines and I'm getting following error: 2020-05-07T16:41:52.9562570Z C:\ Program 文件\ dotnet \ sdk \ 3.1.201 \ Microsoft.Common.CurrentVersion.targets(3032,5): 错误MSB4216:无法运行"GenerateResource"任务，因为 MSBuild无法使用运行时"CLR4"创建或连接到任务主机 和架构"x86".请确保(1)请求的运行时 和/或体系结构在计算机上可用，并且(2) 所需的可执行文件"C:\ Program Files \ dotnet \ sdk \ 3.1.201 \ MSBuild.exe" 存在并且可以运行.

The path exists and there are many files in folder, just not msbuild.exe. There's an msbuild.dll.这是我的Yaml文件:Here's my yaml file:trigger:- masterpool: name: Default demands: msbuildvariables: solution: '**/*.sln' buildPlatform: 'Any CPU' buildConfiguration: 'Release'steps:- task: DotNetCoreCLI@2 displayName: Restore NuGet inputs: command: 'custom' projects: '**/*.csproj' custom: 'restore'- task: MSBuild@1 inputs: solution: '**/*.sln' msbuildLocationMethod: 'location' msbuildLocation: 'C:\Program Files (x86)\Microsoft Visual Studio\2019\Professional\MSBuild\Current\Bin\msbuild.exe' configuration: 'Release' clean: true- task: DotNetCoreCLI@2 displayName: SSP Automated Testing inputs: command: 'test' projects: '**/*Test*.csproj' arguments: '--configuration $(buildConfiguration)' testRunTitle: 'SSP Testing'推荐答案似乎此已知问题.它说On .NET Core, MSBuild doesn't support task hosts of different architectures/runtime versions.提供的解决方法是将CurrentArchitecture/CurrentRuntime添加到 PropertyGroup .看到此类似问题.The workaround provided is to add CurrentArchitecture/CurrentRuntime to PropertyGroup. See this similar issue. <PropertyGroup Condition="'$(MSBuildRuntimeType)' == 'Core' Or '$(TargetFrameworkIdentifier)' != '.NETFramework'"> <GenerateResourceMSBuildArchitecture Condition=" '$(GenerateResourceMSBuildArchitecture)' == '' ">CurrentArchitecture</GenerateResourceMSBuildArchitecture> <GenerateResourceMSBuildRuntime Condition=" '$(GenerateResourceMSBuildRuntime)' == '' ">CurrentRuntime</GenerateResourceMSBuildRuntime> </PropertyGroup>您还可以尝试仅使用msbuild任务来构建所有项目，因为msbuild适用于.net框架和.net核心.您可以为 Msbuild任务.You also try using msbuild task only to build all your projects, for msbuild works for both .net framework and .net core. You can specify solutions and projects for the solution parameter of Msbuild task.由于您的解决方案中包含.Net框架项目和.Net Core项目.我建议使用 Nuget还原任务来还原解决方案. Dotnet cli无法与.NET Framework一起正常使用，这可能无法还原.net Framework项目.Since there are .Net framework projects and .Net Core projects in your solution. I would suggest using Nuget restore task to restore the solution. Dotnet cli doesnot works properly with .NET Framework, which wil probably fail to restore the .net framework projects.希望上面有帮助！ 这篇关于为什么C:\ Program Files \ dotnet \ sdk \ 3.1.201中缺少msbuild.exe?导致AzureDevOps构建步骤失败的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
