我有一个 jenkins 构建，它可以清理、恢复，然后构建一个单元测试项目。这个项目以及我的其他项目最近已迁移到使用PackageReference. 清洁工作，恢复工作。我验证了 NUnit 存在于%userprofile%/.nuget/packages/. 以下是我的构建脚本中的命令：
msbuild /p:Configuration="Debug" /t:clean OtherProjectName.Test.csproj
msbuild /p:Configuration="Debug" /t:restore OtherProjectName.Test.csproj
msbuild /p:Configuration="Debug" OtherProjectName.Test.csproj
这稍后会产生如下所示的输出：
csc.exe /noconfig /nowarn:1701,1702 /nostdlib+ /errorreport:prompt /warn:4 /define:DEBUG;TRACE /highentropyva+
/reference:<one of my references> /reference:<another one> /reference:<and so on>
/out:obj\Debug\OtherProjectName.Test.dll /subsystemversion:6.00 /target:library /utf8output <a list of source files>
我的项目的构建失败，因为它找不到 NUnit（见下文）。我相信它找不到 NUnit，因为编译命令不包含对 NUnit nuget 包的“/reference”。
error CS0246: The type or namespace name 'NUnit' could not be found (are you missing a using directive or an assembly reference?
我的其他项目确实有 NuGet 包的“/reference”。所以我比较了它们，看看是否有什么明显不同。我确实注意到我的大多数项目一开始都包含这一行：
<Import Project="$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props" Condition="Exists('$(MSBuildExtensionsPath)\$(MSBuildToolsVersion)\Microsoft.Common.props')" />
我认为这可能是罪魁祸首，基于我对这条线的简短阅读，但是当我在本地机器上尝试相同的步骤时（它有 VS2017 和 MSbuild 15，就像 jenkins 服务器一样）我无法复制这个问题.
我的.csproj文件有以下内容：
