What is error "Flag '-' is not valid for 'create project'."?

I am trying to compile a PhoneGap project via command

droidgap create

I constantly receive an error: Error: Flag开发者_开发百科 '-' is not valid for 'create project'..

To be more precise, I do not receive any other errors (like FAILED or similar), but this one only. Also the xxx_android folder does get created in the parent directory.

Can I disregard this message? What does it mean?

This happens on Linux systems if the PhoneGap project is located in directories that have spaces in it, like "/home/username/some dir with spaces/".

It seems that PhoneGap does not handle this well.
