Unable to compile package...UnrealBuildTool failed

Dear All,

I’m a new user of UE4 and im unable to package my project…pls help.

If you clone the project. You can delete old versions from epic launcher. Also delete build, cpp and target files inside of directory: Unreal Engine Projects"Your project name"\Intermediate\Source
I had the same issue. I did this and problem gone. But don’t know how.
