Not a one liner but a two-liner.
This is the technique I use often for displaying paths with <pathconvert> ...
<pathconvert property="p" pathsep="${line.separator}- ">
<fileset dir="." includes="*"/>
</pathconvert>
<property name="listing" value="- ${p}${line.separator}"/>
<echo>${listing}</echo>
The main task just calculates the middle part (${p}) and I have to put
something before and after it.
In your case this is the same:
<property name="list" value="aaa,bbb,ccc"/>
<ac:propertyregex
property="pattern.internal"
input="${list}"
regexp=","
replace="/,**/"
/>
<property name="pattern" value="**/${pattern.internal}/"/>
<echo>Input List : '${list}'</echo>
<echo>Input Pattern: '${pattern}'</echo>
