cannot open source file "Online.h"

Hello,

I’m trying to build project for 4.13.1. I’m constantly getting the same error cannot open source file “Online.h”. I tried everything that I found on forums. This is my build file:

PublicDependencyModuleNames.AddRange(new string] { "Core", "CoreUObject", "Engine", "InputCore", "AssetRegistry", "AIModule", "GameplayTasks" });

    // Uncomment if you are using Slate UI
    PrivateDependencyModuleNames.AddRange(new string] { "Slate", "SlateCore", "Json" });

    // Uncomment if you are using online features
    PrivateDependencyModuleNames.AddRange (new string] { "OnlineSubsystem", "OnlineSubsystemUtils" });

    // To include OnlineSubsystemSteam, add it to the plugins section in your uproject file with the Enabled attribute set to true

    DynamicallyLoadedModuleNames.AddRange(
        new string] {
                    "OnlineSubsystemNull",
                    "NetworkReplayStreaming",
                    "NullNetworkReplayStreaming",
                    "HttpNetworkReplayStreaming"
        }
    );

    PrivateIncludePathModuleNames.AddRange(
        new string] {
            "NetworkReplayStreaming"
        }
    );

I’ve rebuilt entire solution and even add to uproject:

"Plugins": 
	{
		"Name": "OnlineSubsystem",
		"Enabled": true
	},
	{
		"Name": "OnlineFramework",
		"Enabled": true
	}
]

It looks like NMake paths does not include relevant paths. I took the source from Microsoft UWP branch. Please help.
