[UWP] Building multi-platform .appxbundle via MSBuild fails with IL2CPP scripting backend
How to reproduce:
1. Create a new empty project
2. Switch Target platform to UWP
3. Set 'Scripting Backend' to IL2CPP
4. Build the project
5. Open the PowerShell in the Build directory
6. Execute the following commands:
1. $msbuild='C:\Program Files (x86)\Microsoft Visual Studio\2017\Community\MSBuild\15.0\Bin\MSBuild.exe'
2. & $msbuild .\<PROJECT-NAME>.sln /t:"restore,build" /p:"AppxBundle=Always;AppxBundlePlatforms=x86|ARM" /p:Configuration=Master > build.txt 2>&1
3. $LASTEXITCODE
Expected result: "0" is printed out (meaning that the building was successful)
Actual result: "1" is printed out (meaning that the building failed)
Reproducible with - 2017.4.0f1, 2017.4.29f1, 2018.4.3f1, 2019.1.8f1, 2019.2.0b8, 2019.3.0a8
UPDATE:
This is caused by a "feature" in MSBuild were the output directory is nested when performing a multi-platform build. This functionality must be explicitly disabled to build the Unity generated project. The issue is discussed on these MS developer sites:
https://developercommunity.visualstudio.com/content/problem/164983/creating-uwp-appxbundle-works-in-vs-store-wizard-b.html
https://github.com/microsoft/MixedRealityToolkit-Unity/issues/7351
https://github.com/Microsoft/msbuild/issues/2445
To work around this issue pass: "/p:UseSubFolderForOutputDirDuringMultiPlatformBuild=false" on the MSBuild command line.
For example:
& $msbuild .\<PROJECT-NAME>.sln /t:"restore,build" /p:"AppxBundle=Always;AppxBundlePlatforms=x86|ARM" /p:Configuration=Master /p:UseSubFolderForOutputDirDuringMultiPlatformBuild=false > build.txt 2>&1

Some notes from my testing: (2018.4.18f1):
1: Platform="x86";AppxBundlePlatforms="x86";Configuration=Master;AppxBundle=Always;
2: Platform="ARM";AppxBundlePlatforms="ARM";Configuration=Master;AppxBundle=Always;
3: Platform="x86|ARM";AppxBundlePlatforms="x86|ARM";Configuration=Master;AppxBundle=Always;
4: AppxBundlePlatforms="x86|ARM";Configuration=Master;AppxBundle=Always;
5: AppxBundlePlatforms="x86";Configuration=Master;AppxBundle=Always;1 & 2 Build OK (but only for one platform).
3 is an invalid configuration (Only one platform can be specified)
4 (OP) Attempts to build the x86 project to ARM folders - strange. Fails before attempting 'actual' ARM project.
5 Same result as in 4.I have not tested changing the 'Architecture' output between x86 and ARM in the Unity GUI - though I presume this would result in the same (reverse) error.
A cursory glance suggests this is an msbuild limitation as much as a unity one.
