Packing a NuSpec file

I’m converting a part of our build which depended on using nuget pack on a nuspec file directly to use dotnet pack. I’ve read a number of threads on this, including dotnet/sdk#5525, and none seem to fit the scenario I have here.

The nupkg I’m trying to build is for the Roslyn compiler tools. This is a collection of projects which are built separately. There is no single project that builds the entire set of binaries that I can attach a <NuspecFile> entry too.

I’ve tried creating a dummy csproj file just to drive the NuSpec file argument but that’s not working:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>netcoreapp2.0</TargetFramework>
    <NuspecFile>Microsoft.NETCore.Compilers.nuspec</NuspecFile>
  </PropertyGroup>
  <Target Name="Build" />
</Project>

Attempting to run dotnet pack on this project still tries to build the project. That’s a huge step backwards for us. Particularly because there are ~30 nuspec files we need to migrate. Adding 30 new dummy builds is excessive here.

How can I use a nuspec file for a project that has no reasonable build story?

This has come up before: supporting nuspec directly without a csproj file. I suggest filling an issue on nuget/home for that.
