deleting files not in whitelist

[Jason Guild <ja...@alaska.gov>]

Hello:

I have a build file which declares a <resources> containing a list of 
expected files which are relative to some directory. I am trying to 
delete any files from that directory which /are not present/ in the 
<resourcelist>, and I can't figure out how to do that with the <delete> 
task and my understanding of the standard selectors.

Here's my resource list:

    <resources id="my-whitelist">
         <resourcelist basedir="${some.dir}">
             <url url="${target.files.url}"/>
         </resourcelist>
    </resources>

Basically my-whitelist is simply a list of filenames which are expected 
to exist relative to ${some.dir}.

In a target, I would like to somehow use the <delete> task to delete any 
files found in ${some.dir} which are /not listed in/ "my-whitelist", 
like this:

    <delete dir="${some.dir}">
         <not>
             <resources refid="my-whitelist"/>
    </not>
    </delete>

But this doesn't work. I also tried:

    <delete>
         <restrict>
             <fileset dir="${some.dir}"/>
             <rsel:not
    xmlns:rsel="antlib:org.apache.tools.ant.types.resources.selectors">
                 <resources refid="my-whitelist"/>
             </rsel:not>
         </restrict>
    </delete>

Which doesn't work either.
Any help you can provide would be appreciated.

Thanks,
Jason

Sorry for not having the right time to digg into your solution.

Two workaround come into my mind:

1. Copy your whitelisted files into a tmp directory, delete the whole src directory and copy the whitelisted files back

2. Use <pathconvert> to convert your whitelist to an excludes-clause and use <delete><fileset .. excludes="${whiteliste.excludes}"/>
