Sample Ant Build File - WAR
You
can also group all the property values in a separate properties
file and include it in the ant build file. Here the build.properties
file contains all the property values.
Remember the property value is immutable, so if you set a property
value in the properties file you cannot change it in the build
file. This give more control over the build process.
The build.properties file.
web.dir=WebContent
web.lib.dir=${web.dir}/WEB-INF/lib
build.classes.dir=build/classes
dist.dir=dist
project.name=AntExample3
Use the property task to include the properties file in the Ant
build file.
<property
file="build.properties" />
Here is the complete build file for your reference.
<?xml
version="1.0" ?>
<project
name="AntExample3" default="war">
<property
file="build.properties" />
<path
id="compile.classpath">
<fileset
dir="${web.lib.dir}">
<include
name="*.jar"/>
</fileset>
</path>
<target
name="init" depends="clean">
<mkdir
dir="${build.classes.dir}"/>
<mkdir
dir="${dist.dir}" />
</target>
<target
name="compile" depends="init" >
<javac
destdir="${build.classes.dir}" debug="true"
srcdir="src">
<classpath
refid="compile.classpath"/>
</javac>
</target>
<target
name="war" depends="compile">
<war
