Hi Jason,

Howdy,
I've been looking at reporting in Maven 3.x and I've been following
the work
that Vincent Massol has been doing over at XWiki where he has made
some
attempts at melding Doxia, the XWiki rendering engine, and
WikiModel. You
can see the proposal here:
http://dev.xwiki.org/xwiki/bin/view/Design/RenderingEngineConvergence
I am looking to remove the Doxia dependency from Maven 3.x so that
reporting
is removed from core and just becomes another set of components.
Having
I definitely agree to decouple Maven from Doxia, or conversely :)
We actually have a lot of problems due to this coupling, see MNG-3402.
Doxia coupled to Maven is not very nice so in the next couple
releases of
the Maven 3.x alphas the hard dependency on Doxia will be removed.
This will
open the door for anyone who wants to add a different mechanism.
Doxia
reports will still work, I'm not planning on removing the
functionality just
unbinding it from the core. But that opens the door for something
new!
Some questions to clarify what you have in mind:
- how do you plan to integrate reporting concretely to Maven 3?
As a completely separate execution environment. So the plugin manager
in 3.x will only deal with build plugins. Then a separate plugin
manager can be created for Doxia based reports and those will map to
the current reporting element. Then I would like to create another
execution environment for a more data centric report model.
- what about the backward compatibility in the reporting plugins?
I will make the basic support to start but my interest lies in a data
centric model for reporting. The more document centric approach I
think has progressed further in XWiki and WikiModel. I would
personally like to feed the data collected into something simple for
producing reports.
What I personally think the best path would be is to help what
Vincent has
started. There are really only three people here who work on Doxia,
the
releases are very slow in coming and I think you would immediately
double or
Agree but we work when we have time :)
Sure, but I think you would benefit by having a team that is focused
on this full-time. I don't see any downside as then your additional
part-time efforts help something that the XWiki folks are working on
all the time.
@Dennis: what are your availabilities to release the version 1.0?
After this release, 1.1 could be out, IMHO all stuffs are there.
triple the size of the team merging with the XWiki folks and
getting the
WikiModel developer as well. This is what the XWiki folks do all
the time
and I think you would get some more velocity in the progress of the
project
as a whole. Vincent is using Plexus for his stuff so it's not that
wildly
different but I think you would get more visibility over there and
a higher
The xwiki proposal seems to move the Doxia code to the xwiki umbrella,
so do you plan to do it?
I don't work on Doxia so I'm not going to do anything. I'm going to
focus on data production and once I do that I'll figure out how I'm
going to produce reports. I think there are good things in Doxia,
XWiki, and WikiModel so a hybrid of the three systems is probably the
best path forward.
@Vincent, could you clarify why a fork is not possible for you?
Cheers,
Vincent
degree of collaboration. I think you would also get a model that is
more
complete for things like blogs, wikis, and books.
Any thoughts? I've CC'd Vincent too as I'm not sure he's on this
list.
Thanks,
Jason

People develop abstractions by generalizing from concrete examples.
Every attempt to determine the correct abstraction on paper without
actually developing a running system is doomed to failure. No one
is that smart. A framework is a resuable design, so you develop it by
looking at the things it is supposed to be a design of. The more
examples
you look at, the more general your framework will be.
