It's weird that it tries to create a 'core/core.pro' and 
'core/core.pro.shared', I don't have any such files here.

Is it correct that directory 
'/home/hossein/Projects/libreoffice/core/core/' does not exist? (which 
would explain the error messages when trying to create the files, but 
not why this is attempted at all...).

I'll try that here to see how it behaves for me when I take those steps, 
then run 'make qtcreator-ide-integration'.

Can you possibly send me your 'workdir/GbuildToJson/' so I can see 
whether there's anything obviously weird in there?
