Having slightly changed markup from default
<ItemGroup Condition=" '$(PackageSources)' == '' ">
<PackageSource Include="https://nuget.org/api/v2/" />
<PackageSource Include="\\server\share\" />
How does nuget treat these sources? If by some reason build server's account it works under has no permission to the share will it throw NotAuthorized or will swallow it and throw PackageNotFound?
Also please confirm that it doesn't require escaping, e.g.
