Hi,

Is there a way to specify which build file to use within a target?

I use my local machine for building the war for the development
environment and the production one. The properties are picked up from
build.properties but I have to change this file each time depending on
where I am going to deploy to.

I would like separate tasks, one for each environment, and within the
target specify which property file to use (eg dev.properties,
prod.properties).



Add a property into the mix to hold the name of the props

<target name="load-server-props">
 <fail unless="server.name">No server</fail>
 <properties file="conf/${server.name}.properties "/>
</target>

<target name="war" depends="load-server-props">
 <war ...>
</target>

At the same time, I want to warn you about the perils of having different WAR files for different destinations, as you can be sure that the wrong version will eventually get onto the wrong box. There are better approaches from the most advanced, SmartFrog : http://people.apache.org/~stevel/slides/oscon.pdf , to a simpler technique I've used in the past: having a properties file for each system in the WAR file, and having the webapp load these dynamically based on their hostname.
