I have urgent problems with svnant

I have used "svnant- 1.0.0" and I copy svnjavahl.jar, svnClientAdapter.jar, and svnant.jar files to folder c:/ant/lib.Then I wrote code like this in build.xml

     <target name="checkout_this">
             <svn username="${svnant.repository.user}" password="${svnant.repository.passwd}"& gt;
           &nb sp;       <checkout url="${svnant.this.url}" revision="HEAD"                           &nbs p;            &n bsp;         destPath="src_${svnant.version}" />
     &nbs p;     </svn>
    </target>
 

and I run command prompt by "ant checkout_this" command. After that I got message like this

             Buildfile: build.xml

          &n bsp;  checkout_this:

          &n bsp;  BUILD FAILED

          &n bsp; c:\ant\work\project\build.xml:39: Cannot use javahl nor command line svn client

which code at line 39 is

" <svn username="${svnant.repository.user}" password="${svnant.repository.passwd}"& gt;"

So, I find answer of this error from Internet and I understood that I must copy intl3_svn.dll, libapr.dll, libapriconv.dll, libaprutil.dll, libdb44.dll, libeay32.dll, libsvnjavahl- 1.dll, ssleay32.dll files to c:\ant\bin folder and then I run command prompt with same command again.

The result output message are

Buildfile : build.xml

checkout_this:
