I just wanted a place to park an experiment until I have something I can
show the dev list, but the idea is that we need to retain dynamism at
least in the build section of the POM. I don't think it's appropriate
for the whole POM, as this could really damage determinism...for
instance, plugins should not be able to add dependencies to projects,
since this hurts our ability to manage the project-dependency relationships.
Since the project can change in legitimate ways during the course of a
build - especially for forked executions, such as changing the build
directories - that means that expressions used to configure subsequent
plugin executions MUST be synchronized to the internal state of the
project itself. This is problematic when we interpolate all of these
expressions up front, since we lose the dynamism. So, I'm experimenting
with interpolating the POM without the build section up front, then
interpolating the build section for each plugin execution, and
back-propagating the changes to that section into the original,
uninterpolated Build instance for future plugin executions.
It's a little heavy, but I haven't been able to imagine any other way
out of this without changing the APIs used to manipulate project data.
In the longer term, I think that's the right way forward, but or 2.0.x I
don't want to force a massive re-release party for the plugins.
At any rate, I'm planning to write it all up and submit it to the dev
list once I have working code that people can look at. I'm currently 4
ITs short of that.

Interesting - I've thought a bit about this myself, though not for
2.0.x. What are you working towards?
