This is certainly possible. Depending on what exactly you are trying to do,
your method to acheive it may differ. Here is one method I use to get the same
thing done in different environments.
I create a properties file for each environment:
dev.properties
test.properties
In the properties files, I put environment specific stuff, like the following:
dev.properties
###############
HOSTNAME=localhost
DEPLOYPATH=C:\some\path\to\deploy\stuff\
DOSOMETHING=TRUE
Then I would have a build.xml that looks like this:
<project name="example" default="build">
<available file="${env}.properties" property="prop.file.exists"/>
<fail unless="prop.file.exists">Can't find ${env}.properties</fail>
<property file="${env}.properties"/>
<target name="build" depends="dosomething">
<!-- Do stuff here using the properties set in ${env}.properties -->
</target>
<target name="dosomething" if="DOSOMETHING">
<!-- Do not set DOSOMETHING in the ${env}.properties if you don't need this
done. -->
</target>
</project>
Then I call ant with the following command:
ant -Denv=dev build\
The dosomething target will always get called, but will only execute if the
DOSOMETHING property is set. So I don't set this in test.properties, perhaps.
I hope this helps,
