Paket.Restore.targets error MSB4064: The "Readme" parameter is not supported by the "PackTask" task loaded from assembly: NuGet.Build.Tasks.Pack, Version=5.6.0.5,

Description

I have an error when building a solution by msbuild.exe
C:\Agents\agent1\_work\5\s\Tests\.paket\Paket.Restore.targets(368,15): error MSB4064: The "Readme" parameter is not supported by the "PackTask" task loaded from assembly: NuGet.Build.Tasks.Pack, Version=5.6.0.5, Culture=neutral, PublicKeyToken=31bf3856ad364e35 from the path: C:\Program Files\dotnet\sdk\3.1.302\Sdks\NuGet.Build.Tasks.Pack\Desktop\NuGet.Build.Tasks.Pack.dll. Verify that the parameter exists on the task, the <UsingTask> points to the correct assembly, and it is a settable public instance property. Paket.Restore.targets(322,5): error MSB4063: The "PackTask" task could not be initialized with its input parameters.

Repro steps

1. My Solution has projects netstandard2.0 with GeneratePackageOnBuild and projects .netcore3.1, Framework 4.6.2.
   csproj:

<TargetFramework>netstandard2.0</TargetFramework>
<GeneratePackageOnBuild>true</GeneratePackageOnBuild>

2. Paket version 7.2.1+8e4eb74b42fbd45f39f7afce9184c16ebb65f16c
3. paket restore and dotnet restore
4. restore generated Paket.Restore.targets

Known workarounds

Visual Studio Build Tools 16.11.27

Start by reproducing the provided msbuild.exe command with the listed global.json SDK versions and inspect .paket/Paket.Restore.targets around lines 322 and 368. Compare the generated PackTask inputs, especially Readme, with the loaded NuGet.Build.Tasks.Pack assembly; done means the solution builds successfully without MSB4064 or MSB4063.
