Command line build problem

Question

We have a large help project I'm migrating to RoboHelp 6
(nearly 3000 topics, 12 chms plus a master file). We generate using
a script that calls the command-line option. One of the projects
fails during command line processing, even though I can build it
from within the GUI without fail. When I run the command line
command, this is the message that is returned:
"D:\quartus\robohelp\subs\reference>"d:\Adobe\RoboHelp
6.0\RoboHTML\RHCL.exe" reference.xpj
Adobe (R) RoboHelp Project Command Line Compiler version
6.00.099
Copyright (C) 2006 Adobe Macromedia Software LLC. All rights
reserved.
Project: D:\quartus\robohelp\subs\reference\reference.xpj
Layout: Microsoft HTML Help.
Output: D:\quartus\robohelp\reference.chm.
Scanning project for compilation....
Error: Failed to scan all the project files. Please use
RoboHelp to recover the project.
Unexpected Error: Failed to prepare single source data for
RHCL. Please try to compile it in RoboHTML."
If I open the project in the GUI and compile it, then compile
from the command line, it works fine. But if I clear the directory,
run the NGCMD.exe command and get the files out and run the
RHCL.exe, I get the same error message.
Thanks

Finally I figured out this problem.
It is because one .fpj file missing in the image folder.
When I was using X5, there is no image.fpj in the image
folder, but after upgrading to RH6, using the command line compiler
will fail if there is no the .fpj file under the image folder.
Checking in the image.fpj to the server, then check it out to
your build machine, everything is OK now.
