【问题描述】：
在构建项目时出现此错误。
错误 NETSDK1004 资产文件 'J:\Test\core\fx-core\obj\project.assets.json' 未找到。运行 NuGet 包还原以生成此文件。 FxCore C:\程序 Files\dotnet\sdk\3.1.201\Sdks\Microsoft.NET.Sdk\targets\Microsoft.PackageDependencyResolution.targets 234
为了解决这个问题，我在包管理器控制台中运行命令dotnet restore。但是在运行时出现以下错误。
PM> dotnet restore J:\Test\core\fx-core\FxCore.csproj(3,3)：警告 MSB4011：“C:\程序 Files\dotnet\sdk\3.1.201\Current\Microsoft.Common.props" 不能 再次导入。它已经在“C:\Program 文件\dotnet\sdk\3.1.201\Sdks\Microsoft.NET.Sdk\Sdk\Sdk.props (40,3)"。 这很可能是构建创作错误。随后的导入 将被忽略。 C:\程序 文件\dotnet\sdk\3.1.201\Sdks\Microsoft.NET.Sdk\Sdk\Sdk.targets(37,3)： 警告 MSB4011：“C:\Program Files\dotnet\sdk\3.1.201\Microsoft.CSharp.targets" 无法导入 再次。它已经在“J:\Test\core\fx-core\FxCore.csproj (118,3)"。这很可能是构建创作错误。这随后 导入将被忽略。 C:\程序 Files\dotnet\sdk\3.1.201\NuGet.targets(124,5)：错误：值不能 空值。 (参数'文件夹名称') [J:\Test\core\fx-core\FxCore.sln] PM>
如何解决这个问题？

【问题讨论】：
-
最终，这与为这个项目/项目设置构建文件的人有关......在许多非标准情况下，某处有一个“构建”文件可以做这些事情，或者一些关于构建它的注释
-
@MarcGravell 感谢您的评论。我怎样才能继续修复它？请解释一下
-
这就像说“我的代码有问题；我该如何解决？” - 如果不进行大量查找，我们无法回答这个问题；如果我记得，你从某个地方克隆了这个 - 我会从那里开始：是否有“如何构建”文件？有可以查看的 CI 构建吗？你能问作者吗？
-
事情是这样的：正常/标准构建将正常工作 -
dotnet restore和dotnet build，你就完成了；所以不管这是什么：它不是一个正常/标准的构建；他们可以在那里做字面上的任何事情。深入了解它可能很困难，坦率地说，扔掉 csproj（只是 csproj，而不是实际代码）并从头开始重新组合起来可能更容易。但是对于这个问题没有简洁的“这就是你如何做”的答案，因为它取决于很多细节 -
哦，任何 .targets、.props 等文件都可能导致异常
