UE4 requires the NuGet Package Manager

I success to build the first two images on windows server 1804. But in the third, I have, at step 7 an error message . UE4 requires the NuGet Package Manager to be installed to use "C:\Program Files (x86)\Microsoft Visual Studio\2017\BuildTools\MSBuild\15.0\Bin\MSBuild.exe". Please run the Visual Studio Installer and add it from the individual components list (in the 'Code Tools' category).

Maybe you have to include Nuget Package Manager into the first container ?

This appears to be related to the recent release of Visual Studio 2017 version 15.8, since this error does not occur when using a build of the ue4-build-prerequisites image from a few weeks ago that contains version 15.7.6 of the Build Tools. Presumably Microsoft have altered the dependency lists in such a way that the NuGet Package Manager is no longer a required dependency of the default selected installation workloads.

I have modified the Build Tools installation command to explicitly specify the required installation workloads and components, including the component ID for the NuGet Package Manager. This ensures that NuGet is always installed, and should be less brittle in the face of future Visual Studio updates. As an added bonus, this has also reduced the overall size of the ue4-build-prerequisites image by about 15GB, since only the required installation workloads are selected.

To utilise this fix, you will need to pull the latest version of the Dockerfiles and rebuild all images by specifying the --rebuild parameter when invoking the build script.
