Not sure if it's the same issue exactly, but I get the same error message when I try to use the external NuGet client after previously having used the in-process one (either by changing cake.config or by using the --nuget_useinprocessclient flag).
I can solve the issue by fully deleting the tools folder and then re-running .\build.ps1.

[asbjornu]

We're experiencing this problem quite often in GitVersion and I would like it to go away. If deleting the tools folder helps, I'd love to implement that in our TearDown task. I just wonder what the path to the tools folder to delete is?

[augustoproiete]

@asbjornu You get the path to the tools folder via Context.Configuration.GetToolPath(...);

You can use the static context:

var toolsPath = Context.Configuration.GetToolPath(Context.Environment.WorkingDirectory, Context.Environment);
Information("Tools Path: {0}", toolsPath);

Or access the context through the target:

Task("Build")
    .Does((context) =>
    {
        var toolsPath = context.Configuration.GetToolPath(
            context.Environment.WorkingDirectory, context.Environment);

        Information("Tools Path: {0}", toolsPath);
    });

RunTarget("Build");

@asbjornu If you can help repro this behavior it would be great so we can try to fix it.

[asbjornu]

Thanks, I'll try that. You can see the error here. It happens quite often in our actions.

[asbjornu]

@augustoproiete, as you can see by asbjornu/GitVersion@2d59fb8, cleaning the tools directory does not seem to fix the problem. Ideas?

[jifb]

Same here.

OS: Win 10, 64-bit
Cake: 0.38.2, 32-bit
Nuget: 5.10, 5.11 [Edit]

I'm getting the same error as this: https://gitter.im/cake-build/cake/archives/2018/03/05?at=5a9d26fd0a1614b712e3248b

I'm invoking
cake.exe build.cake -nuget_source=D:\... --nuget_useinprocessclient=false --WD=D:\... --configuration=Release --Verbosity=Diagnostic --Target=... (and further custom -- arguments)

this is invoking
nuget.exe install Cake.Git -OutputDirectory D:/... -Source D:\... -Version 0.21.0 -ExcludeVersion -NonInteractive
(yes, right, forward / and backward \ slashes mixed)

When I run this nuget command right afterwards it succeeds (because everything is already installed.

And: @starkcolin is right, the errors goes away when deleting all from tools directory (keeping packages.config) [Edit: it would be a better solution not to see a crash, even if there's something in the tools directory. This is a matter of nuget, isn't it?]
