还原管道: DotNetCoreCLI‘AzureDevOps’忽略Directory.Build.props文件

Question

我们正在从NetFramework项目切换到具有多个TargetFrameworks的NetCore项目。如果Directory.Build.Props包含为net40或net35编写的代码，则需要一个TargetFramework文件。Directory.Build.Props中引用的NuGet包来自NuGet.org。

由于NuGetCommand是为NetFramework构建的，因此我们正尝试在yaml管道中从使用NuGetCommand切换到DotNetCoreCLI。然而，DotNetCoreCLI 'restore‘似乎不包括Directory.Build.props中的NuGet包。还原任务可以工作，但生成任务会失败，并显示以下错误：

Answer 1

请使用dotnet生成任务中的--no-restore选项禁用隐式还原。

这里是document：dotnet restore命令在显式恢复有意义的某些场景中仍然有用，例如Azure DevOps服务中的持续集成构建，或者在需要显式控制恢复发生的构建系统中。

此外，dotnet restore在内部使用与.NET Core SDK打包在一起的NuGet.exe版本。dotnet restore只能恢复在.NET核心项目.csproj文件中指定的包。如果您的解决方案中还包含Microsoft .NET框架项目，或者使用package.json指定依赖项，则还必须使用NuGet任务来还原这些依赖项。请参考this document。
