MSBUILD : Task factory warning NMSBT010: There is a mismatch between SDK NuGet version (4.9.2) and the NuGet version the task factory was compiled against (4.8.0). There might occur some exotic errors.

Hello,

Issue strikes back with new dotnet core sdk (i'm using 2.2.101). Warning is followed by an error:

Furthermore, I've tried the latest beta version (4.0.1-beta1-53), which targets Utilpack 2.9.1:

error MSB4175: The task factory "UtilPack.NuGet.MSBuild.NuGetTaskRunnerFactory" could not be loaded from the assembly "C:\Users\mjasni\.nuget\packages\utilpack.nuget.msbuild\2.9.1\build\\netcoreapp1.1\UtilPack.NuGet.MSBuild.dll". Assembly with same name is already loaded

My Project targets net462 due to some libraries that we're required to use, but we use aspnetcore (wanted to upgrade to 2.2 when faced the issue). I'd appreciate any suggestions how to fix the issue.

Hi @czeslav87 , can you submit a minimal repro and/or a log with /verbosity set to detailed if not even diagnostic?

Edit: Either here or make an issue on https://github.com/stazz/UtilPack :)

[czeslav87]

Will do my best to provide repro asap.

Repro is blank dotnetcore2.2 console app with GitVersion task. Must run on new .net Core SDK to reproduce bug.

Best regards.

Ah yes, the 4.0.0 version of GitVersionTask will definetly not work on new dotnet, as it uses outdated UtilPack. From the log.txt:

"C:\Users\mjasni\.nuget\packages\gitversiontask\4.0.0\build\functionality\GitVersionBuild.targets" from project "C:\Users\mjasni\source\repos\GitVersionBugRepro\GitVersionBugRepro\GitVersionBugRepro.csproj" (target "CoreCompile" depends on it):
                   Initializing task factory "UtilPack.NuGet.MSBuild.NuGetTaskRunnerFactory" from assembly "C:\Users\mjasni\.nuget\packages\utilpack.nuget.msbuild\2.7.0\build\\netcoreapp1.1\UtilPack.NuGet.MSBuild.dll"

Version 2.7.0 is not compatible with newer dotnet versions.

I tried updating to GitVersionTask 4.0.1-beta1-53 which has newest UtilPack dependency, but it seems that it is missing some required stuff in its build/netstandard2.0 folder and/or from .nuspec. I manually downloaded and added libgit2-a904fc6.so and LibGit2Sharp.(dll|pdb|xml) files to the build/netstandard2.0 folder of 4.0.1-beta-53 version of GitVersionTask, and I ended up with:

So it successfully used NuGet API to restore the package, and started running it. It failed to load the managed assembly, but that is due the fact that it was not really part of any NuGet package, as I manually copied it. But I think this is one thing that definetly will need some improving - smarter native package dependency resolution.

In any case, this seems to be more about version 4.0.1-beta1-53 of GitVersionTask not to have LibGit2Sharp dependency in its .nuspec file under .NETStandard2.0 framework dependency specification, and also about UtilPack not being able to pick up on the manually added native library.

Can you confirm you get as far as this with 4.0.1-beta1-53 version of GitVersionTask, after you fully clean repro project, @czeslav87 ?

P.S. The Detected current NuGet framework to be ".NETCoreApp,Version=v2.0" is probably due to the fact that automatic .NET Core App 2.2 deduction does not work since the 2.2 is still so new. It can be overridden tho, and I'll add the auto-deduciton support for 2.2. as well soon. But I think #1537 needs to be at least agreed on how to proceed, before that.

[czeslav87]

@stazz yes, I'm having the same results with 4.0.1-beta1-53. LibGit2Sharp Is missing

Fun thing is, if you manually add dependency to the GitVersionTask.nuspec of 4.0.1-beta1-53 version of GitVersionTask, so it will look like this:

    <dependencies>
      <group>
        <dependency id="UtilPack.NuGet.MSBuild" version="2.9.1" exclude="Build,Analyzers" />
      </group>
      <group targetFramework=".NETStandard2.0">
        <dependency id="UtilPack.NuGet.MSBuild" version="2.9.1" exclude="Build,Analyzers" />
        <dependency id="YamlDotNet" version="5.2.1" exclude="Build,Analyzers" />
        <dependency id="LibGit2Sharp" version="0.26.0-preview-0070" exclude="Build,Analyzers" />
      </group>
      <group targetFramework=".NETFramework4.6.1">
        <dependency id="UtilPack.NuGet.MSBuild" version="2.9.1" exclude="Build,Analyzers" />
      </group>
    </dependencies>

There will be no errors. :)

same issue here. any fixes?

[stazz]

The GitVersionTask version 4.0.1-beta1-58 seems to have correct .nuspec file.

@bonesoul Have you tried settings /verbosity to detailed? I think that error is originally coming from another.

@czeslav87 It looks like the UtilPack is loading assemblies OK, but first there is a warning about StrictFilePathMarshaler (maybe LibGit2Sharp is missing some new .NET Core feature?), and finally ends up with The "GetAssemblyVersion" task was not given a value for the required parameter "NuGetVersion". Setting /verbosity to detailed would help here too.

Edit: I'll try to get work started related to #1537 this weekend. Hopefully soon it will be possible to lock down NuGet version in .NET Core, thus avoiding quite a lot of confusion as .NET Core versions keep changing.

[czeslav87]

I've just looked up StrictFilePathMarshaller error, and results led to this #720 . I'll check it out tommorow. I might have had opened two instances of VS with different project with GitVersionTask.
