Conditional Question for Build Script

All,

I have a situation where I need to perform a check as to whether or not
a file needs to be included in build based upon a property.  The
property would represent the environment, either "stage" or "prod".
Based upon the value of that property, I would need to rename a file and
move it to a different directory.  Can anyone let me know the best way
to do this?  Thanks.

Daniel

Lets assume the the default behaviour is to *not* set a propery named
"production" to some value.  You could then setup something like:

  <condition property="production.isSet" value="true">
    <isset property="production"/>
  </condition>

If the product property is set then the production.isSet condition is true.
Otherwise it is false.  Your target can then declare a guard. Fopr example:

  <target name="whatever" depends="whatever-prod,whatever-stage"/>

  <target name="whatever-prod" if="production.isSet">
    <echo>Doing something with 'prod' mode.</test>
  </target>

  <target name="whatever-stage" unless="production.isSet">
    <echo>Doing something with 'stage' mode.</test>
  </target>

Cheers, Steve.

You can use the <if> task (part of the ant-contrib project).
 
<if>
   <equals arg1="${destination}" arg2="stage"/>
   <then>
        // Things to do if destination==stage
   </then>
   <else>
        // Things to do if destination==stage
   </else>
</if>

Or you can use the <switch> task  :-)
