Running parallel targets in Ant loop
Hi,
I need to run multiple target in Ant's loop. How can I achieve this. I am
able to make antcall in sequential way as described below.
<target name="run">
<for begin="1" end="2" param="idx">
<sequential>
<antcall target="run-test">
</antcall>
</sequential>
</for>
</target>
But I need to do performance testing where i need to call multiple targets
with various values of idx. If I change sequential to parallel, i get
following error:
C:\Eclipse3.1\eclipse\Workspace\AntProject\d6\build.xml:53: Invalid type
class org.apache.tools.ant.taskdefs.Parallel used in For task, it does not
have a public iterator method
Is there any way to achieve what I desire. i.e running parallel targets with
different value of idx (As sometime I had to run multiple targets sometime
up to 30).

Thanks for replying...
But using <parallel> within for loop (see how I used it below) is not
serving my purpose... It is firing antcall's sequentially... I want to run
multiple instances of target "run-test" with different values for id
param....
<target name="run">
<for begin="1" end="2" param="idx">
<sequential>
<parallel>
<antcall target="run-test">
</antcall>
</parallel>
</sequential>
</for>
</target>

Yes it is working with attribute parallel="true"... :)_
Thanks a ton Peter... :)

You could use the "parallel" attribute ->
http://ant-contrib.sourceforge.net/tasks/tasks/for.html
WARNING:: although I wrote the task, I have never used the parallel
attribute, since
most of ant is not parallel safe.

you can use <parallel> task..

Harry, put the parallel inside the sequential. They aren't a pair where
you would choose one or the other. The sequential task has hooks that
let the loop structure set the variable for you. Inside sequential, you
can access idx as @{idx} rather than the more usual ${idx}
<sequential>
<parallel/>
<parallel/>
</sequential>

Hi,
I need to run multiple target in Ant's loop. How can I achieve this. I
am
able to make antcall in sequential way as described below.
<target name="run">
<for begin="1" end="2" param="idx">
<sequential>
<antcall target="run-test">
</antcall>
</sequential>
</for>
</target>
But I need to do performance testing where i need to call multiple
targets
with various values of idx. If I change sequential to parallel, i get
following error:
C:\Eclipse3.1\eclipse\Workspace\AntProject\d6\build.xml:53: Invalid type
class org.apache.tools.ant.taskdefs.Parallel used in For task, it does
not
have a public iterator method
Is there any way to achieve what I desire. i.e running parallel targets
with
different value of idx (As sometime I had to run multiple targets
sometime
up to 30).
