P.S. :
using $attributes.get('in').split(',') because i assumed
your list is given comma separated, f.e. like being set via
<property name="mylist" value="name1,name2,ant,forum,nabble"/>

/*
[..]
How can i access the the newlist here (outside <groovy> task)
I tried ${list}
But it is giving old values .. which is set initially..
please do reply.

using ruby as scripting language, but it's similar for any scripting
running with BSF, means simply use the ant api.
So for using your newlist outside your script task you have to set
a new property with its value for further processing in your ant script
example with ruby =
<scriptdef name="mylistutil" language="ruby">
<attribute name="in"/>
<attribute name="out"/>
<attribute name="filter"/>
if $attributes.get('filter').nil?
$project.setProperty $attributes.get('out') ,
$attributes.get('in').split(',').reverse.join(',').to_s
else
$project.setProperty $attributes.get('out') ,
$attributes.get('in').split(',').
reject!{|i| i =~ /#{$attributes.get('filter')}/}.reverse.join(',').to_s
end
</scriptdef>
and then if filtering (filter attribute takes a regex) wanted just use scriptdef
with filter attribute, f.e. =
<mylistutil in="${mylist}" out="newlist" filter="2$"/>
filters all elements ending with 2 and gives newlist =
nabble,forum,ant,name1
<mylistutil in="${mylist}" out="newlist"/>
runs without filtering and gives newlist =
nabble,forum,ant,name2,name1
*** if you want to overwrite your property mylist, then use mylist in out
attribute
and ${mylist} (which is immutable normally) will get overwritten, f.e.
<mylistutil in="${mylist}" out="mylist"/>
