ivysvn: file organization and passwords

Question

I'm looking at using ivysvn to help us use a local ivy repository in our svn repository.

I found this tutorial which I found easy to follow, and almost works, except for 3 points:

1. The tutorial has a blank username and password. How can I get this to work with our SVN repository (which does not allow anonymous commits) without having to put my username and password in the ivysettings.xml or build.xml? The closest I could think of was to use in ivysettings.xml:

   <svn name="ivysvn"
            repositoryRoot="{{{deleted}}}"
            userName="${svn.user.name}" userPassword="${svn.user.password}" 
            binaryDiff="false">
         <ivy pattern="[organisation]/[module]/[revision]/ivy.xml"/>
         <artifact pattern="[organisation]/[module]/[artifact].[ext]"/>
    </svn>
   

   and then at the command prompt do

   ant -Dsvn.user.name={{{deleted}}} -Dsvn.user.password={{{deleted}}} publish 
   

2. I thought the organization of the repository was as follows (for example suppose the server URL is http://someserver/svn/cache/ivy , the organization is Yoyodyne, and the module is HappyFunBall)

   http://someserver/svn/cache/ivy/
     Yoyodyne/
       HappyFunBall/
         1.0/
           ivy.txt
           libraries here
   

   This would imply in ivysettings.xml

       <ivy pattern="[organisation]/[module]/[revision]/ivy.xml"/>
       <artifact pattern="[organisation]/[module]/[revision]/[artifact].[ext]"/>
   

   and not

       <ivy pattern="[organisation]/[module]/[revision]/ivy.xml"/>
       <artifact pattern="[organisation]/[module]/[artifact].[ext]"/>
   

   Which is correct? Ideally there would be a mapping of SVN version # to artifact revision, and then you wouldn't need to create [revision] directories, but something doesn't make sense.

3. The blog post had, in the source project, an ivy.xml file with this:

    <ivy:publish resolver="ivysvn"  forcedeliver="true" 
         overwrite="true" publishivy="false">
           <!-- defines the location from where the libraries 
           are to be picked up from for publishing -->
     <artifacts pattern="lib/[artifact].[ext]"/>
   </ivy:publish>
   

   and I think I understand all of it except for the publishivy="false" part, since the retrieval part wouldn't work except when I changed it to publishivy="true". Which is correct? Where does the ivy.xml file come in w/r/t putting a copy of it into the repository?
