Subject Re: setting var's in a property file
Date Thu, 28 Aug 2003 17:51:01 GMT
There are several possibilities :
in ant-contrib there is a propertycopy task which can expand ${something} in
a property value
you can also manipulate your property file with :
- the propertyfile task (under optional tasks in ant)
- you can try your luck with the replace task or the replaceregexp task.
Note that the replace task does not expand properties if you use CDATA in
the tokens currently. (known bug).

- My prefered path would be the one with the loadproperties
with nested filterchain.
Actually there is an expandproperties filter and a replacetokens filters,
one of them should provide the functionality you want.
