Ant: Passing attributes to Build.xml
Critter on a previous post asked "if you can pass in attributes to the build.xml file?" From the Terminal this is as easy as adding another argument "-D".
-D<property>=<value>This will update a property in you build.xml file with the value you passed in For example you would use something similar to
1 ant -buildfile ~/desktop/build.xml -DechoMsg=NewEchoMessage
Putting this into practice here is a sample build.xml which I am going to save to my Desktop
1 <?xml version="1.0" encoding="UTF-8"?>
2 <project name="myProject" default="runEcho" basedir=".">
3
4 <property name="echoMsg" value="I am the original message" />
5
6 <target name="runEcho">
7 <!-- Simply echo's a message to the screen -->
8 <echo message="${echoMsg}"/>
9 </target>
10 </project>
From the Terminal no run
2 <project name="myProject" default="runEcho" basedir=".">
3
4 <property name="echoMsg" value="I am the original message" />
5
6 <target name="runEcho">
7 <!-- Simply echo's a message to the screen -->
8 <echo message="${echoMsg}"/>
9 </target>
10 </project>
1 ant -buildfile ~/desktop/build.xml -DechoMsg='I overwrite the echo message'
In your terminal window you should see something like
1 Buildfile: [PATH TO BUILD FILE]build.xml
2
3 runEcho:
4 [echo] I overwrite the echo message
5
6 BUILD SUCCESSFUL

I've taken the old Model-Glue Ant script you had and modified it a bit.. I've downloaded the latest and placed it on my computer.. made these modification: @modelglueapplicationtemplate@ to all the necessary files..
so now I can call my build.xml and pass in the directory name where I want M-G to be built..
