I'm trying to solve the same problem and have it mostly working; the only
problem I can't solve is to allow a task for one sub-project depend on a
task for another.
Apart from that, it's pretty easy. Just use a build.xml that loads a
properties file and make all your worker tasks use properties exclusively.
For example:
<project name="master build" default="all">
<properties file="${component.properties}/>
<target name="all" depends="compile,jar,..."/>
<init>
<classpath id="classpath">
<fileset dir="${dir.lib}">
<include name="**/*.jar"/>
</fileset>
</classpath>
</init>
<target name="compile" depends="init">
<javac
srcdir="${dir.src}"
destdir="${dir.build}"
classpathref="classpath"
includes="net/**/*.java"
/>
</target>
...
</project>
Invoke ant with
ant -Dcomponent.properties=path-to-component.properties ...
Each component's properties file defines properties the build.xml needs, for
example:
dir.build=build/component1
dir.lib=component1/lib
dir.src=component1/src
You could get fancy by using ant-contrib's 'foreach' class to build all of
your components by searching for their properties files.
