Unable to Install Derby

[ram]

Hi All,
I tried to install Derby and followed all the instructions given at this link:-
http://svn.apache.org/repos/asf/db/derby/code/trunk/BUILDING.txt

I installed all the required softwares (except the optional packages).
I have setup all the environment variables also.

But when I run command "ant" then it gives me error:-
-----------------------------------------------------------------------------------
Unknown argument: -cp
ant [options] [target [target2 [target3] ...]]
Options:
  -help, -h              print this message
  -projecthelp, -p       print project help information
  -version               print the version information and exit
  -diagnostics           print information that might be helpful to
                         diagnose or report problems.
  -quiet, -q             be extra quiet
  -verbose, -v           be extra verbose

  -nice  number          A niceness value for the main thread:

------------------------------------------------------------------------------------------------

It is showing me "ant" help instead of running the command. Kindly help me in this regard. I have to install Derby very urgently.

Thanks and Regards,
