+ | DESCRIPTION |
+ For automating my project, I needed a way to do some stuff
+ on all files in a fileset, and so I implemented AntCallOn
+ which I've been using for some time now, an thought I'd share
+ the code with the Ant team...
+
+ As an example, I show how to call ant for all subprojects.
+
+ ==-- example --==
+ <taskdef name="antcallon" classname="AntCallOn"/>
+ <target name="main">
+ <antcallon target="main-sub" base="${PRJ.home}/">
+ <fileset dir="${PRJ.home}">
+ <include name="*/build.xml"/>
+ <exclude name="setup/build.xml"/>
+ </fileset>
+ </antcallon>
+ </target>
+ <target name="main-sub">
+ <echo message="fileext = ${fileext}"/>
+ <echo message="filedir = ${filedir}"/>
+ <echo message="reldir = ${reldir}"/>
+ <echo message="filename = ${filename}"/>
+ <echo message="filebase = ${filebase}"/>
+ <echo message="running ant in ${reldir}"/>
+ <ant dir="${reldir}"/>
+ </target>
+
