Hi,
as there's still no post how to achieve what you
need with vanilla ant ...

... i wrote a small ruby script for that purpose
might be used for backups too
you need available for ant (simply put
in %ANT_HOME%/lib )=
1. the BeanScriptingFramework (bsf.jar) as for
all other scripting langueages (groovy,javascript,
beanshell ...), get it here =
http://jakarta.apache.org/bsf/
2. the jruby-complete-1.0.jar, as it contains all
needed ruby libraries the script includes with
'require ...' (like import in java)
the normal jruby.jar will not be enough
get it here =
http://dist.codehaus.org/jruby/
Notice =
1. the distributed jruby-complete-1.0.jar is build
with jdk1.5, so if you're running with 1.4, you'll
get a "Unsupported major.minor version 49.0"
** i'll ask the developers to provide a version for 1.4
in the meantime you may try to backport it with
retroweaver, get it here =
http://retroweaver.sourceforge.net/
(mostly it's only 1.5 because they used StringBuilder and stuff)
2. Ant properties are referenced as $propertyname in jruby,
if you have 'dotted' properties, i.e $my.dotted.property
you have to use $project.getProperty('my.dotted.property')
Script, see ruby code in <script>, runs also with ruby
interpreter outside ant
first step : recursive copy of srcdir to destdir
renaming inplace might be dangerous, if error your
srcdir is corrupted
second step : replace pattern for dir/subdir names in destdir
changing filenames and dir/subdir names also possible, see
comment in script
finally you may delete your srcdir
example, sorry if formatting gets corrupted =
-------------------------------------------------
<?xml version="1.0"?>
<project name="bla" default="main">
<property name="srcdir" value="J:/test"/>
<property name="destdir" value="J:/test_"/>
<property name="torepl" value="foobar"/>
<property name="replwith" value="foobaz_"/>

def rename(headOfTree, what, withWhat)
p = Pathname.new(headOfTree)
p.find() do |file|
path = file.to_s
File.rename(path, path.gsub(what,withWhat)) if
path.include?(what) && File.directory?(file)
end
end
Dir.mkdir(destdir) unless File.exists?(destdir)
Dir.entries(srcdir).each do | i |
if i !='.' && i !='..'
FileUtils.cp_r Dir["#{srcdir}/**"], destdir
end
end
Find.find(destdir) do |file|
rename(file,torepl,replwith)
end
]]>
</script>
</target>
<target name="main" depends="depends">
<echo>
copied = ${srcdir}
to = ${destdir}
replaced = ${torepl}
with = ${replwith}
</echo>

-------------------------------------------------
result =
srcdir
J:\>dir /S/B test
J:\test\bla.txt
J:\test\foobar
J:\test\sub1
J:\test\foobar\asdf.txt
J:\test\foobar\foobar
J:\test\foobar\subsub2
J:\test\foobar\foobar\foobar
J:\test\foobar\subsub2\foobar
J:\test\foobar\subsub2\foobar.txt
J:\test\sub1\bla.txt
destdir looks like
J:\>dir /S/B test_
J:\test_\bla.txt
J:\test_\foobaz_
J:\test_\sub1
J:\test_\foobaz_\asdf.txt
J:\test_\foobaz_\foobaz_
J:\test_\foobaz_\subsub2
J:\test_\foobaz_\foobaz_\foobaz_
J:\test_\foobaz_\subsub2\foobar.txt
J:\test_\foobaz_\subsub2\foobaz_
J:\test_\sub1\bla.txt
