[UWP] IL2CPP build incorrectly sets Output Directory and Intermediate Directory paths

Windows Store Apps


When trying to publish a build or generate the App Package with enabled option "Generate app bundle" for a UWP build, the following error shows up:

C:\Program Files (x86)\Windows Kits\10\bin\x64\MakePri.exe Dump -IndexFile C:\USER\temp_builds\cubetest_3\Win10UniCubeTest\\..\build\obj\Win10UniCubeTest\ARM\Release\split.pri -OutputFile C:\USER\temp_builds\cubetest_

C:\Program Files (x86)\MSBuild\Microsoft\VisualStudio\v14.0\AppxPackage\Microsoft.AppXPackage.Targets(1433,5): error APPX0002: Task 'ExpandPriContent' failed. Could not find a part of the path 'C:\USER\temp_builds\cubetes
t_3\Win10UniCubeTest\build\obj\Win10UniCubeTest\ARM\Release\split.pri.xml'.\r [C:\USER\temp_builds\cubetest_3\Win10UniCubeTest\Win10UniCubeTest.vcxproj]

Reproducible with 5.3.3, 5.4.0 versions.

Repro steps:
1. Build an empty project with the following settings

Platform: Windows Store
SDK: Universal 10
UWP Build Type: D3D or XAML
Scripting Backend: IL2CPP

2. Open generated project and create app package "Project->Store->Create App Packages".
Set "Generate app bundle" option to "Always", select any platform (ARM, x86 or x64), solution platform "Release" or "Master" and press create.

3. Error appears in the error list.

To fix this change the solution settings for
Output Directory and Intermediate Directory (Configuration Properties -> General -> Output Directory and Intermediate Directory.) from:
$(ProjectDir)\..\build... to


Note no slash after build. The TargetName is hardcoded as well for no reason.
