Distributed HLOD builds always fail for projects not under the Engine Root

Distributed HLOD builds always fail for projects not under the Engine Root

Description

In BuildProject.txt, to make relative path to the project outside the engine root, all paths contains “..” after action command directory. 

D:/dev/UnrealEngine-5.5.0//HLODTemp/f09bf0f5/HLODBuilder0/Add/../ue505projects/HLODBuild/Content/__ExternalActors__/P_Map/C/LZ/FL19HG6OH72SGCTU6CPVMA.uasset
D:/dev/UnrealEngine-5.5.0//HLODTemp/f09bf0f5/HLODBuilder0/Add/../ue505projects/HLODBuild/Content/__ExternalActors__/P_Map/7/YN/URONVCZMYBHYUH731YM3MF.uasset

D:/dev/UnrealEngine-5.5.0//HLODTemp/f09bf0f5/HLODBuilder0/Add/../ue505projects/HLODBuild/Content/__ExternalActors__/P_Map/C/O9/KFBUT22OLJFZWSRMIKRH8C.uasset

As the ".." cancels the action directory, the HLOD builder lost the action command.

Steps to Reproduce
  1. create a project outside the engine root
    ex.)
    + UnrealEngine-5.5.0
        +Engine
    + MyProjects
        + MyHLODTest
            + MyHLODTest.uproject
  2. Open the editor
  3. Create a world partitioned level
  4. Save the level
  5. Quit the editor
  6. run following batch file to build HLOD with -DistributedBuild option
set PROJECTFILE=D:\dev\ue505projects\HLODBuild\HLODBuild.uproject
set UNREALEDITORCMD=D:\dev\UnrealEngine-5.5.0\Engine\Binaries\Win64\UnrealEditor-Cmd.exe
set MAP=/Game/P_Map
%UNREALEDITORCMD% %PROJECTFILE% %MAP% -run=WorldPartitionBuilderCommandlet -AllowCommandletRendering -builder=WorldPartitionHLODsBuilder -DeleteHLODs
%UNREALEDITORCMD% %PROJECTFILE% %MAP% -run=WorldPartitionBuilderCommandlet -AllowCommandletRendering -builder=WorldPartitionHLODsBuilder -DistributedBuild -SCCProvider=None -SetupHLODs -BuilderCount=1
%UNREALEDITORCMD% %PROJECTFILE% %MAP% -run=WorldPartitionBuilderCommandlet -AllowCommandletRendering -builder=WorldPartitionHLODsBuilder -DistributedBuild -SCCProvider=None -BuildHLODs -BuilderIdx=0
%UNREALEDITORCMD% %PROJECTFILE% %MAP% -run=WorldPartitionBuilderCommandlet -AllowCommandletRendering -builder=WorldPartitionHLODsBuilder -DistributedBuild -SCCProvider=None -FinalizeHLODs

Result

Errors are reported in the BuildHLODs step :
