2.6.1.  Example

Suppose you want to use the a library file (my-custom-tasks-*.jar) which contains version and build informations and don't want to modify the build file everytime you use a new version of it.

build.xml

<?xml version="1.0"?>

<project basedir="." name="properties-test" default="main">

<taskdef classpath="orangevolt-ant-tasks-1.3.2.jar" resource="com/orangevolt/tools/ant/taskdefs.properties"/>

<target name="main">

<!--

find the jar file and put its name

into property "custom-tasks-jarfile"

-->

<find dir="lib"

file="my-custom-tasks-*.jar"

nameProperty="custom-tasks-jarfile"

/>

<!--

use the jar file name

to load the tasks and taskdefs

-->

<taskdef resource="custom/tasks/taskdefs.properties">

<classpath>

<pathelement path="."/>

<pathelement location="lib/${custom-tasks-jarfile}"/>

</classpath>

</taskdef>

</target>

</project>
