--------------------------------
Hi: Ralph
May be I'm missing something on:
quote:
1. Resolving any variables provided via system properties (variables from
parents won't be found since the parent isn't known.
So, what I understand is, the variables in the parent are still not getting
expanded.?
If so, I would like to make the following suggestion. We don't have to evaluate
variable in parent at the time... Today, when I give
a variable in parent, mvn gets stuck at searching for ${parent} in the repo.
in the default project builder. Isn't that simple enough to replace the
${parent} with system property , or project.properties. Once a valid value is
found in either of these, one can update the project model with right parent
info. Isn't it?
I will try 2.1 and let you know.
thanks..
