Obtaining properties

["Hayes, Peter" <Pe...@fmr.com>]

Hi,

I would like to obtain a property by using another property to get it.

I have a prop file like this
---------------------
proj1.run.main = com.xxx.Project1
proj2.run.main = com.xxx.Project2
---------------------

In my build.xml I would like to figure out which project to run based on a
passed in property.  (-Dproject=proj1)

So in my target would be something like

<property name="main" value="${project}.run.main" />

But instead of main being set to the string "proj1.run.main" I would like to
'dereference' that so it would get the previously set value
('com.xxx.Project1') 

Is this possible w/ ANT

Thanks.

Did you try:

<property name="tempMain" value="${project}.run.main" />
<property name="main" value="${tempMain}" />

??

I can't think of any way right off-hand to do what you want (doesn't mean
there isn't a way, just that I can't think of one real quick :) -- but
wouldn't it be easier to just set "main" to "com.xxx.${project}" and
define ${project} with -Dproject="Project1"?
