conditional loading of properties files

[Julian M. Savage]

I'm wondering if there is any way to conditionally load a properties file.   I have two files, build.xml and test.properties in my example below, and as you can see, while defining the property deploy prevents the echo from being executed, it doesn't prevent the property file from being loaded, which is somewhat counter-intuitive. Is this expected/required behaviour?   Thanks,   Julian.   Example:   # build.xml <project name="fisci" default= "prepare" basedir=".">         <target name="init.user" unless="deploy">                 <echo message="init.user"/>                 <property file="${user.home}/test.properties"/>         </target>           <target name="init" depends="init.user">                 <echo message="init"/>                 <property name="test.port" value="4100"/>         </target>           <target name="prepare" depends="init">                 <echo message="prepare"/>                 <echo message="test.port=${test.port}"/>                 <tstamp/>         </target> </project> EOT # test.properties test.port=1234   $ ant prepare Buildfile: build.xml   init.user: init.user   init: init   prepare: prepare test.port=1234   BUILD SUCCESSFUL   Total time: 0 seconds $ ant -Ddeploy=yes prepare Buildfile: build.xml   init.user:   init: init   prepare: prepare test.port=1234   BUILD SUCCESSFUL   Total time: 0 seconds
