Sample Ant Builds

Below are two Ant builds for Java Web JEE projects, using default Eclipse folder structure. Each copies some files that need to be different in the Test vs. Prod build. These were run using Ant 1.8. I'm not indicating these use "best practices," just some that worked for me.

Ant Build.xml One

<project name="myproject" default="dist" basedir=".">

 <property name="project.name" value="MyProject" />
 <property name="dist.dir" location="dist" />
 <property name="dist.prod.dir" location="${dist.dir}/prod" />
 <property name="dist.test.dir" location="${dist.dir}/test" />
 <property name="conf.prod" location="conf/prod" />
 <property name="conf.test" location="conf/test" />
 <property name="web.dir" location="WebContent" />
 <property name="web.lib" location="${web.dir}/WEB-INF/lib" />
 <property name="web.script" location="${web.dir}/scripts" />

 <path id="classpath">
  <pathelement location="${web.lib}/jstl.jar"></pathelement>
  <pathelement location="${web.lib}/standard.jar"></pathelement>
 </path> 

 <target name="dist">
  <tstamp />
  <echo message="${ant.project.name}: ${ant.file}" />
  <delete dir="${dist.dir}"/>
  <mkdir dir="${dist.test.dir}"/>
  <mkdir dir="${dist.prod.dir}"/>
  
  <echo>Building PROD war file</echo>
  <copy file="${conf.prod}/script/validate.js" tofile="${web.script}/validate.js" 
   overwrite="true" />
  <copy file="${conf.prod}/WEB-INF/web.xml" tofile="${web.dir}/WEB-INF/web.xml" 
   overwrite="true" />
  <war destfile="${dist.prod.dir}\${project.name}.war" webxml="${web.dir}\WEB-INF\web.xml">
   <fileset dir="${web.dir}" />
  </war>
  
  <echo>Building TEST war file</echo>
  <copy file="${conf.test}/script/validate.js" tofile="${web.script}/validate.js" 
   overwrite="true" />
  <copy file="${conf.test}/WEB-INF/web.xml" tofile="${web.dir}/WEB-INF/web.xml" 
   overwrite="true" />
  <war destfile="${dist.test.dir}\${project.name}.war" webxml="${web.dir}\WEB-INF\web.xml">

  </war>
  <echo>${ant.project.name} build complete</echo>
 </target>

</project>
