Performance of Ant
Hi,
On a professional product build scripts, we see the need for calling many
times <antcall> to call a particular target. However due to isolation level
for this target calls.. there is a huge penalty on performance.
Is there a way to call another target in the same build context and with no
isolation needed.
For now we are using the custom task which calls project.executeTarget()..
which seem to invoke the target in the same build context and hence
performance is too great.
However in case ant forum feels such a need.. it would be nice to have
antcall to have another option or another tag which does exactly this.
Regards,
Raja Nagendra Kumar,

I think you've misunderstood what I was trying to say. ant-contrib
already has such a task:
<http://ant-contrib.sourceforge.net/tasks/tasks/runtarget.html>
*/
There's also the <call> task from Antelope, see =

Oops.. It is nice to know that ant-contrib already has it.

This message never reached the ant-contrib-developers mailing list, see
<http://sourceforge.net/mailarchive/forum.php?forum_name=ant-contrib-developers>
- maybe the list doesn't support Nabble.

Hi Stefan
I have put the summary of discussion and need for a new task as per this
discussions in ant-contrib.
The same is available at

If you have question about ant-contrib's task(s), then their forum will
be better suited than this list, yes.

Any ability to call directly makes the build file more procedural. The
depends attribute is declarative. Ant's goal is to be declarative in
nature.
I will note that the ant-contrib project provides a task to invoke a
target.
If you find yourself calling targets with different parameters it
usually really means you need some sort of task that doesn't exist.
macrodef is a way to write a task in Ant instead of a real programming
language.

Hi Stefan,
This could be one workaround due to lack of straight approach to call the
target.
I am surprised why such a thing did not exist from day one.. Pl. let me know
if this approach has any ant design related issues.
I see macros are callable directly, targets would also be called though
dependents , but with in the target calling another target is not straight
(isolation principles are being applied in all the existing tasks antcall,
subant, ant).
For now we did write light wait target call as custom task and preformance
has improved a lot (in over case there were 6 ant calls)

Nagendra

If you mean Project#createTask doesn't work for macrodef-ed or
presetdef-ed tasks - this is true.

Yes, I could but I loose the flexibility of calling from command line.
To our surprise.. when such a changes are done, they work from xml but it
does not work custom task (based on project.createTask() and execute() )
methods.

Isn't there any way you could turn your target into a <macrodef>?
