Ya, having plugins being able to talk to each other in abstract ways
would be very good...
But for this... its should be able to check the last modified + size
to see if it really needs to cp or not. Its a minor detail, but will
help for large projects where seconds spend with the copy could be
saved.

Subject: Mvn always install's jar when nothings changed?
Why does mvn always install a new jar file when the original jar file
did not change? Would be nice if it could skip this step to speed up
large multi-module builds when only single module (or few modules)
have
changes.
Same goes for handling copying resources... seems like mvn spends a
bunch of time copying them (usually when filtering is enabled) when
there are no changes to be made. In Ant terms I could have use a n
uptodate task and a linked target to only copy (or install) these
things
when something has changed.
Why has Maven moved away from this kind of handling of build tasks?
Re-running a build takes much, much longer than is really needed in
many
cases, especially when only a class here and there is changed.
Are there any plans to address some of these issues and hopefully
speed
up rebuilds for Maven projects?
