I have a big project with many subprojects in it.
I've written a build.xml for each subproject and one build.xml for the main
project.
A lot of these subprojects are dependent on each other.
Lets say I have subprojects A,B,C,D,E and F.
A is dependent on B and C.
B is dependent on D.
C is dependent on D and E.
D is dependent on E.
F is dependent on E.
Now I want that the individual build.xml files for each subproject should
completely build that subproject.
For that I've used <Ant> task.
So the compilation target of each build.xml depends on a target which calls
ant for all the other subprojects that need be there.
Now when I am writing the build.xml for the main project, I want to build
all the subprojects.
Here again I am using the <Ant> task.
The problem here is that ant calls the target again and again for a
subproject every time it comes in the dependency of another subproject. This
increases the build time considerably even when the subprojects are already
uptodate.
I tried to solve this problem by setting a property in every subproject and
checking it whenever it is called again. But I have now discovered that the
property set during one ant call does not carry forward to the other one.
How can I solve this problem ?

I did exactly the same thing too, for the subprojects.
Though it appears a bit odd that a target should call a target in the parent
file which again calls a target back in the same file, but it works. And is
pretty neat too.

Yupe I got similar problem as well and that is how I solved the problem.
However the problem arise when I tried to compile from the sub-project, I
then make the target on the subproject call the top most level. fe:
<project name="main" basedir=".">
<target name="build-A" depends="build-B, build-C">
<ant antfile="dirA/build.xml" dir="dirA"/>
</target>
</project>
and in B:
<project name="B" default="build" basedir=".">
<target name="build">
<ant antfile="../build.xml" target="build-B/>
</target>
</project>
I wonder what other people has done for similar thing.
Regards,
Victor

I had written the build files for the subprojects in a way, such that the
subproject build files had the dependency information in themselves.
Something like
(build.xml for A)
<target name="prepare">
<ant antfile="../dirB/build.xml" dir="dirB"/>
<ant antfile="../dirC/build.xml" dir="dirC"/>
</target>
<target name="compile" depends="prepare">
<javac...../>
</target>
and similarly other build files too.
But now I realise that your design is much neater.
(Its my first brush with ant or make system of any kind. Couldn't think of
such a basic thing.)
Thanks for the tip.
It would certainly make things simpler.

So are you saying that something like
<project name="main" basedir=".">
<target name="A" depends="B,C">
<ant antfile="dirA/build.xml" dir="dirA"/>
</target>
<target name="B" depends="D">
<ant antfile="dirB/build.xml" dir="dirB"/>
</target>
<target name="C" depends="D,E">
<ant antfile="dirC/build.xml" dir="dirC"/>
</target>
<target name="D" depends="E">
<ant antfile="dirD/build.xml" dir="dirD"/>
</target>
<target name="E">
<ant antfile="dirE/build.xml" dir="dirE"/>
</target>
<target name="F" depends="E">
<ant antfile="dirF/build.xml" dir="dirF"/>
</target>
</project>
wouldn't work for you?
