Oops. s/<properties file/<property file/

We use a separate properties file for each environment, and have common
property names. Instead of integ.transfertype, stage.transfertype, etc, I
would just have 'transfertype' and it would have different values in the
different files. Then the Ant script has targets based on the possible
values of the property, and one generic parent target that calls them.
Example:
<properties file="${envname}.properties" />
<target name="deploy">
<antcall target="deploy-${transfertype}" />
</target>
<target name="deploy-nfs"> ... </target>
<target name="deploy-ssh"> ... </target>
envname determines which environment-specific properties file needs to be
read.
This is a more scalable solution. Adding a new environment is as simple as
creating a new properties file.
This assumes the build has already occurred and you can make run the
deployment Ant script separately for each environment.
