HELP: EnvVarsToXML error using UnrealBuildTool on OS X + MONO

Hi everyone,
wondering if somebody can help me …
I’m on OSX, using Unreal Engine 4.12, i’ve installed mono and i want use Codelite as default IDE for C++ scripting.

With UnrealBuildTool.exe i want generate codelite workspace, using this command:

mono /Users/Shared/UnrealEngine/4.12/Engine/Binaries/DotNET/UnrealBuildTool.exe -codelitefile -project="/Users/alessandroelia/Documents/Unreal Projects/Invasori/Invasori.uproject" -game -engine

but when i run, i obtain this log + error:

Discovering modules, targets and source code for project…
UnrealBuildTool Exception: ERROR: /Users/Shared/UnrealEngine/4.12/Engine/Source/Programs/EnvVarsToXML/EnvVarsToXML/EnvVarsToXML.csproj doesn’t exist!

Any Idea how to solve this?
