copied!<p>An alternative to making a template is to evolve one by gradually generalising your current project's Ant script so that there are fewer changes to make the next time you copy it for use on a new project. There are several things you can do.</p> <p>Use ${ant.project.name} in file names, so you only have to mention your application name in the project element. For example, if you generate myapp.jar:</p> <pre><code><project name="myapp"> ... <target name="jar"> ... <jar jarfile="${ant.project.name}.jar" ... </code></pre> <p>Structure your source directory structure so that you can package your build by copying whole directories, rather than naming individual files. For example, if you are copying JAR files to a web application archive, do something like:</p> <pre><code><copy todir="${war}/WEB-INF/lib" flatten="true"> <fileset dir="lib" includes="**/*.jar"> </copy> </code></pre> <p>Use properties files for machine-specific and project-specific build file properties.</p> <pre><code> <property file="/etc/ant/build.properties" />  <property file="build.properties" />  <property name="jboss.home" value="/usr/share/jboss" /> ... </code></pre> <p>Note that Ant properties cannot be changed once set, so you override a value by defining a new value <em>before</em> the default value.</p>
