make -D in ant?

[ro...@elastica.com]

Can I parse in parameters from the command line?

Why can't I do this

<project name="plymedia" basedir="${rootDir}">

and 

ant -DrootDir=C:\plymediadev

I want to hide all references to absolute paths outside of the build file.

when I do this it doesn't evaluate $rootDir as I would expect.

Because Ant doesn't evaluate ${} constructs in attributes of project
and target. At least not in Ant 1.2.

The simple workaround, don't specify a basedir in you build file at
all:

<project name="plymedia">

and

ant -Dbasedir=C:\plymediadev

What can we expect? It would definately be nice to be able to pass in 
properties from the command line especially for baseDir or for that
matter anything else. I don't want to keep these references in the 
.xml file.

Ok this is what I was getting at with my last post (albeit poorly).  Ant 1.2
only seems
to evaluate properties at creation time.  However I would propose a more
dynamic system
where properties were recursively evaluated whenever used.

i.e. in this case when ${basedir} used it would lookup basedir in the hash,
get the value
of ${rootDir},  and the try to extract rootDir from the hashmap and find
C:\plymediadev.

Its a simple change,  I was just wondering if it had already been thought of
and done/shot down
for some glaring reason I could not see.
