Use nuspec version information from custom target - msbuild

Question

I'm trying to use the dotnet CLI to pack and publish packages for one of our solutions. I've created a target to do this so that each project in the solution can use it. The target looks like this:
<Target Name="PackAndPublishPackages" AfterTargets="AfterBuild" Condition=" '$(Configuration)' == 'Release' And '$(IsDesignTimeBuild)' != 'false' ">
<PropertyGroup>
<NuspecFile>$(MSBuildProjectName).nuspec</NuspecFile>
<NuspecProperties>Configuration=$(Configuration);Platform=$(Platform)</NuspecProperties>
</PropertyGroup>
<Exec Command="del $(MSBuildProjectDirectory)\$(PackageOutputPath)*.nupkg" />
<Exec Command="dotnet pack $(MSBuildProjectDirectory)\$(MSBuildProjectName).csproj --no-build" />
<Exec Command="dotnet nuget push $(MSBuildProjectDirectory)\$(PackageOutputPath)*.nupkg -k key -s http://url/" />
</Target>
The target runs as I would expect each time, but it doesn't appear to use the version information from the provided nuspec file or the listed nuspec properties defined in the property group when running dotnet pack. I've confirmed that the file exists in the directory for each project.

Answer 1

You defined the PropertyGroup at the scope of your target, which only set the property when the target runs.
Did you try to move it outside of the target?
<PropertyGroup>
<NuspecFile>$(MSBuildProjectName).nuspec</NuspecFile>
<NuspecProperties>Configuration=$(Configuration);Platform=$(Platform</NuspecProperties>
</PropertyGroup>
<!-- later in your csproj -->
<Target Name="PackAndPublishPackages" AfterTargets="AfterBuild" Condition=" '$(Configuration)' == 'Release' And '$(IsDesignTimeBuild)' != 'false' ">
<Exec Command="del $(MSBuildProjectDirectory)\$(PackageOutputPath)*.nupkg" />
<Exec Command="dotnet pack $(MSBuildProjectDirectory)\$(MSBuildProjectName).csproj --no-build" />
<Exec Command="dotnet nuget push $(MSBuildProjectDirectory)\$(PackageOutputPath)*.nupkg -k key -s http://url/" />
</Target>
