The required element 'metadata' is missing from the manifest error when doing dotnet pack

I am trying to do create a nuget package by combining .nuspec and .csproj file.

My .csproj file looks like below:

<PropertyGroup>    
    <TargetFramework>netstandard2.0</TargetFramework>
    <Authors>Author name</Authors>
    <Company>Company name</Company>    

    <RepositoryUrl>RepositoryURL</RepositoryUrl>
    <VersionPrefix>0.0.1</VersionPrefix>
    <PackageId>SomeID</PackageId>
    <Description>Description</Description>
    <GenerateAssemblyConfigurationAttribute>false</GenerateAssemblyConfigurationAttribute>
    <GenerateAssemblyCompanyAttribute>false</GenerateAssemblyCompanyAttribute>
    <GenerateAssemblyProductAttribute>false</GenerateAssemblyProductAttribute>    
    <NuspecFile>Projectname.nuspec</NuspecFile>     
  </PropertyGroup>

My .nuspec file looks like following:

<?xml version="1.0"?>
<package>   
   <files>
      <file src=" somefile.json" target="lib" />    
    </files>
</package>

Now, when I try dotnet pack on .csproj file it fails with folllowing error:

The required element 'metadata' is missing from the manifest.

I have also tried couple of things here.

  1. Tried to map properties explicitly as mentioned here:Unable to pack a NuGet package using dotnet CLI and nuspec file but it failed with the same errors

  2. Tried to put explicit metadata tag into the .nuspec file. like <metadata>$PackageId</metadata> hoping that it will fetch $package from .csproj file but that fails with following error:

The required element 'id' is missing from the manifest.

How can I combine both .csproj and .nuspec to do dotnet pack without running into this errors? I am pretty sure it is possible just that I am missing something.

Any suggestions?

The required element 'id' is missing from the manifest.

Solution

  • .nuspec has to have metadata element. It would not build without it. While trying to combine .csproj and .nuspec make sure that the mandatory fields like

    <Authors>Author name</Authors> <Company>Company name</Company> <VersionPrefix>0.0.1</VersionPrefix> <PackageId>SomeID</PackageId>

    are always set in .nuspec. inside metadata tag Not in .csproj.
