Unable to locate repository containing directory during dotnet build or publish

Question

I am adding support for Docker on my ASP.NET Core 2.2 app and while testing the commands for docker locally I've found that the dotnet publish -f netcoreapp2.2 -c Release -o out errors out.

./IdentityServer.sln

./IdentityServer/IdentityServer.csproj: https://gist.github.com/paulcsiki/4d3b827af418044dacea0149a2361b81

Output of dotnet restore on the same folder as the solution:

I've tried running the restore and publish command from the WebApp folder (/Users/paul/docker/IdentityServer) and it yields the same output.

Output of the file /Users/paul/docker/dependencies/identityserver4/src/IdentityServer4.csproj:

Answer 1

The problem was that I have referenced a project called IdentityServer4 which had a reference to the Sourcelink NuGet package which was looking for the .git folder. Removing the package reference has resolved the issue.

Answer 2

I can confirm @Paul solution. I edited the .csproj file and removed the package reference to Microsoft.SourceLink.GitHub:

<Project Sdk="Microsoft.NET.Sdk">
  <ItemGroup>
    <!-- Remove following line: -->
    <PackageReference Include="Microsoft.SourceLink.GitHub" Version="1.0.0-beta-62925-02" PrivateAssets="All" />
  </ItemGroup>
</Project>
