NuGet Package: The specified path, file name, or both are too long.

Hi,

I'm trying TeamCity for the first time and got a build pipeline set up which works fine so far. I now wanted to add a step to create a nuget package but I'm running into the error below:

[pack] NuGet command: C:\TeamCity\buildAgent\tools\NuGet.CommandLine.4.3.0\tools\NuGet.exe pack C:\TeamCity\buildAgent\work\f7bca5d57d919c87\demoproject.charlie.nuspec -OutputDirectory C:\TeamCity\buildAgent\work\f7bca5d57d919c87\build\packages -Properties Configuration=Release

My nuspec file is fairly basic as I just want to see if I can get the package created:

<?xml version="1.0" encoding="utf-8"?>
<package xmlns="http://schemas.microsoft.com/packaging/2010/07/nuspec.xsd">
<metadata>
<!-- Required elements-->
<id>demoproject.charlie</id>
<version>1.0.9</version>
<description>Demoproject charlie project</description>
<authors>The author</authors>

<!-- Optional elements -->
<!-- ... -->
</metadata>
<!-- Optional 'files' node -->
</package>

Does anyone have suggestions on how to fix this issue or what could be the cause of it?

Thanks

Ben
