I am using Hudson on Windows. I am using doxygen plugin. When I specify the
doxyfile location as "crackpot_root_dir/Doxyfile" (where the doxyfile is; my
project's name is "crackpot") and run the plugin I get

Publishing Doxygen HTML results.
FATAL: error
hudson.AbortException: The directory 'C:\Users\.hudson\jobs\Crackpot - Trunk -
Default Config\workspace\docs\doxygen_html' doesn't exist.

The correct location as per the Doxyfile to produce the output is
"C:\Users\g0700201\.hudson\jobs\Crackpot - Trunk - Default
Config\workspace\crackpot_root_dir\docs\doxygen_html".
