Hudson + SvnAnt then i have a problem svnExists can't use

[yu xiaohang]

hello

i wrote ant script for check my version number make sure that it won't be conflict :

			<case value="build">
				<echo>${svn.repo.products}/release_area/${ci.prod.id}_V${prod.version}_REL</echo>
				<!---->
				<fail message="Product exists">	
					<condition>	
						<svnExists javahl="${javahl}" 
								   svnkit="${svnkit}" 
								   target="${svn.repo.products}/release_area/${ci.prod.id}_V${prod.version}_REL"/>		
					</condition>
				</fail>

A true or false Should have been passed to <fail> tag but i found that <svnExists> can only return false wether "${ci.prod.id}_V${prod.version}_REL" exists or not.

i wrote a test script below:

		<condition property="testprop" value="true" else="false">
						<not>
						<svnExists javahl="${javahl}" 
								   svnkit="${svnkit}" 
								   target="${svn.repo.products}/release_area/${ci.prod.id}_V${prod.version}_REL"/>	
						</not>
		</condition>
		<echo>${testprop}</echo>

but wether item exists in subversion repository or not ${testprop} will give false value.

it could be a hudson's bug? or SvnAnt's bug?

someone can help me?
