Hi,

yup, there's a 'hack' with refid's / id's (undocumented)
the ant developers say one shouldn't use it, as it could be
altered in the next ant version.
that said, i use it a lot ;-)

just put the line
<echo message="${toString:classpath}"/>
instead of <echo message="refid classpath"/>
and you have it all on one line separated with ';'

with antcontrib or antelope <for> task you may do things like =

<for list="${toString:classpath}" param="pathitem" delimiter=";">
<sequential>
 <echo>pathitem == @{pathitem}${line.separator}</echo>
</sequential>
</for>

bye4now, Gilbert

P.S.:

if you're using ant regularly subscribe the ant user list - recommended

the antelope tasks should have been merged into antcontrib
but that ain't finished, so i use both.

there might also be another (somewhat 'cleaner') way via <pathconvert>
task that ships with ant, just have a look into the ant manual.
