Sure you can! You can override property definitions in Ant...
What version of Ant are you using !?! Please try to run the following with any Ant 1.x.x
<?xml version="1.0" encoding="ISO-8859-1" ?>
<project name="application" default="build" basedir=".">
<target name="init">
<echo>0: ${a.property}</echo>
<property file="build.properties"/>
<echo>1: ${a.property}</echo>
<property file="build2.properties"/>
<echo>2: ${a.property}</echo>
<property name="a.property" value="last"/>
<echo>2: ${a.property}</echo>
</target></project>
And then tell me what you see if build.properties contains a.property=first ?
My bet (and the CORRECT behavior) is:
init:
[echo] 0: ${a.property}
[echo] 1: first
[echo] 2: first
[echo] 2: firstBUILD SUCCESSFUL Total time: 1 second
Notice that the possible assignment from build2.properties or the explicit property is IGNORED if the property is already defined!
So, please load ${user.home} etc. first!
The user should only have to specify the properties they want that are different from the standard build (if any).
For example:
Lets say I'm happy with all the standard libraries that hibernate provides, but I want to try a new library out. Say I download the latest snapshot of commons-lang.jar from the Jakarta website. Naturally, this snapshot will be more up to date than the one provided by Hibernate, since its newer. So, if it is the only file I want to compile Hibernate against that is different than the default jars, I could have a single entry in my ${user.home}/hibernate.build.properties file:
commons-lang.jar = /my/local/path/to/commons-lang.jar
Every other build dependency would use the standard libraries as specified in Hibernate's default build.properties file.
Isn't this desireable?
