Hi Raja,
That approach wouldn't work well with Ant's immutable properites. It
could lead to bugs that were hard to diagnose, and make build scripts
less portable.
For example, consider an ant script that used a property "libdir",
perhaps something like this:
<property name="libdir" location="lib"/>
If Ant were to pick up environment variables directly, if this
particular property was defined in the external environment, then that
definition would take precedence, and the build would probably fail,
although the reason would not be immediatly obvious.
