Command-line property overrides with 'location' semantics?

[Patrick Surry <pd...@quadstone.com>]

It seems like specifying a property at the command-line via -D always uses 
'value' semantics, even if the property is declared in the project with 
'location' semantics.  For example, on a windows machine with this project:

<?xml version="1.0"?>
<project name="parameters" default="all" basedir=".">
   <property name="foo" value="c:/some/filename.txt"/>
   <property name="bar" location="c:/some/othername.txt"/>
   <target name="all">
     <echo message="foo = [${foo}] and bar = [${bar}]"/>
   </target>
</project>

So plain 'ant' gives:

     [echo] foo = [c:/some/filename.txt] and bar = [C:\some\othername.txt]

but 'ant -Dbar=/a/b/c' gives:

     [echo] foo = [c:/some/filename.txt] and bar = [/a/b/c]

i.e. it's not converting bar as a location anymore.

Is there any way around this other than re-converting the property in the plan 
(ie. <property name="bar2" location="${bar}"/> ) ?

Thanks,
Patrick

You are correct.
The "declaration" in the build script is ignored as the property has 
already been defined,
so it has "value" semantics.
