What may it be wrong about simply using:
<project name="Foo" default="foo" basedir=".">
<property name="bar" value="default"/>
<target name="foo" description="foo">
<echo message="${bar}" />
</target>
</project>
Since properties are immutable and if it was set in the command line
call it won't change?
Best regards,
Alexander.
