Problem building to HoloLens, getting: Missing precompiled manifest for 'NuGetModule' error.

[MartinHelvig]

When I try to build to HoloLens I get a NuGetModule missing error. I followed this guide to setup a HoloLens project and build.

I have disabled Microsoft Windows Mixed Reality and enabled the Microsoft OpenXR.

Here is the full error:

UATHelper: Packaging (HoloLens): ERROR: Missing precompiled manifest for 'NuGetModule'. This module was most likely not flagged for being included in a precompiled build - set 'PrecompileForTargets = PrecompileTargetsType.Any;' in NuGetModule.build.cs to override.

I'm suspecting this is a regression in the Unreal marketplace: It looks like marketplace builds are missing the Intermediate\Build\HoloLens directory for the Microsoft OpenXR plugin.

I have an update pending (1.1.14) which adds PrecompileTargetsType.Any to NuGetModule.build.cs (per the error message) to see if this addresses the problem. Also following up with the Marketplace team.

Update: This is a regression in how the Unreal Marketplace is packaging HoloLens plugins. They are investigating.

You can workaround this now by building the plugin locally: "C:\Program Files\Epic Games\UE_4.27\Engine\Build\BatchFiles\RunUAT.bat" BuildPlugin -Plugin="C:\Program Files\Epic Games\UE_4.27\Engine\Plugins\Marketplace\MicrosoftOpenXR\MicrosoftOpenXR.uplugin" -package=C:\NewMicrosoftOpenXRBuild -nocompile -VS2019

Then copy C:\NewMicrosoftOpenXRBuild\Intermediate\Build\HoloLens to C:\Program Files\Epic Games\UE_4.27\Engine\Plugins\Marketplace\MicrosoftOpenXR\Intermediate\Build\HoloLens

I just use the plugin uploaded on github and put it in /YourProject/plugins/
