Building SVN to my local repository

Hi

I have downloaded the source code for the Subversion and I want to build
subversion in my local repository. This contain a build file in the
location
"D:\subversion-1.4.6.tar\subversion-1.4.6\subversion\bindings\java\javah
l\build\build.xml" but when I am trying to build it using ANT I am
getting following errors. Can you tell me what I should do to
successfully build Subversion in my local SVN repository.
