.net – NuGet Package Restore cannot find package, has no Source

msbuildnetnugetteamcity

I have a package on my TeamCity NuGet feed, built by TeamCity, but a dependent TC project cannot see it during package restore.

[14:05:02][Exec] E:\TeamCity-BuildAgent\work\62023563850993a7\Web.nuget\nuget.targets(88, 9): Unable to find version '1.0.17.0' of package 'MarkLogicManager40'.

[14:05:02][Exec] E:\TeamCity-BuildAgent\work\62023563850993a7\Web.nuget\nuget.targets(88, 9): error MSB3073: The command ""E:\TeamCity-BuildAgent\work\62023563850993a7\Web.nuget\nuget.exe" install "E:\TeamCity-BuildAgent\work\62023563850993a7\ProductMvc\packages.config" -source "" -RequireConsent -solutionDir "E:\TeamCity-BuildAgent\work\62023563850993a7\Web\ "" exited with code 1.

Note that the source parameter in the NuGet command line is empty. Could this be the cause?

Best Answer

As of today, NuGet.targets has the following way to specify custom feed(s):

<ItemGroup Condition=" '$(PackageSources)' == '' ">
    <!-- Package sources used to restore packages. By default, registered sources under %APPDATA%\NuGet\NuGet.Config will be used -->
    <!-- The official NuGet package source (https://nuget.org/api/v2/) will be excluded if package sources are specified and it does not appear in the list -->

    <PackageSource Include="https://nuget.org/api/v2/" />
    <PackageSource Include="\\MyShare" />
    <PackageSource Include="http://MyServer/" />
</ItemGroup>

Another option is to put NuGet.config next to the solution file:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
  <packageSources>
    <add key="nuget.org" value="https://www.nuget.org/api/v2/" />
    <add key="MyShare" value="\\MyShare" />
    <add key="MyServer" value="http://MyServer" />
  </packageSources>
  <activePackageSource>
    <add key="All" value="(Aggregate source)"  />
  </activePackageSource>
</configuration>
