This is how I'd approach the problem.
(I haven't tried it, so there may be some bugs in there):
<project name="topLevel">
<property name="product" value="xyz" description="Default to product xyz.
Overload in command line if required" />
<property name="abcd" value="build/esrst/build_abcd.xml" />
<property name="xyz" value="build/ccp/build_xyz.xml" />
<macrodef name="copyProperty">
<attribute name="property" />
<attribute name="srcProperty" />
<sequential>
<fail unless="@{srcProperty}" message="There isnt a property called
@{srcProperty}" />
<property name="@{property}" value="${@{srcProperty}}"
</sequential>
</macrodef>
<copyProperty property="BUILD_FILE" srcProperty="${product}" />
<target name="javabuild" >
<ant antfile="${BUILD_FILE}" inheritAll="true" target="javabuild" />
</target>
<target name="deploy" >
<ant antfile="${BUILD_FILE}" inheritAll="true" target="deploy" />
</target>
</project>

Subject: Re: Passing multiple targets from one build.xml to another build.xml
What I meant by I have only build xml, is I dont have build_abcd.xml and
neither I have build_xyz.xml.
Say that I have just build.xml with some targets defined.
And Iam not invoking any other build xml from this build.xml, that being
the case
ant understands howmany ever targets I give dynamically.
The moment I invoke one build.xml from other, ant is not able to understand
any of the targets passed unless I explicitly define
each of the target as you mentioned.
Just like in Java where we have varargs, ant should be having something,
otherwise in the simple case(where Iam not invoking one build from other)
how come ant was able to understand multiple dynamic targets, whereas the
same its not able to understand in the case of invoking one build from
another
thanks
