No, for several reasons.
(1) You have no control about the order in which they get executed.
(2)
<execon executable="ant">
<arg value="-f" />
<srcfile/>
<fileset dir="." includes="**/build.xml" />
</execon
Looks like the far more obvious choice.
(3) You are forking a new JVM for every build file. Several <ant>
tasks would run the builds in the same VM and therefore improve build
time considerably.
Apart from "avoid recursive builds" - as this really is not Ant's way
of thinking, this is trying to make Ant fit with the Makefile model -
there is not too much ATM apart from my (2) above.
An <ant> task that would use a fileset to identify subbuilds is on the
wishlist for upcomming implementations.
