I've created a new Hudson job in 1.220 and added 2 CVS modules to it and I've
specified an ANT-based build with a specific, relative path for the ANT file:

CVS modules are: com.profidatalab.nightbird com.xnife.build

The ANT build file is specified as: com.xnife.build/build.xml

When I execute the build, it fails with the following console output:

It has failed to start the cmd.exe program in the following directory: C:
\Documents and Settings\dis\.hudson\jobs\xnife\workspace
\com.profidatalab.nightbird\com.xnife.build

This directory is nonsense. Rather than finding the ANT build file relative to
the job's working directory, Hudson has added BOTH CVS modules as
subdirectories.

I require 2 modules because one of them contains generic build scripts that I
will require for pre and post build steps and the other is specific to what's
being built.

I really like what I've seen and read about Hudson, but this seems a very basic
bug. Is there a workaround for this problem?
