Would it make sense for some bug plugins (like Lucene search) to have

Sure but this can be done with a single branches/ and tags/ dirs. See
https://svn.apache.org/repos/asf/maven/plugins/
Hi Vincent,
thanks for your work.

of having
one per plugin which is a maintenance nightmare. This is
what we're doing for Maven and it seems to be working fine. See
http://svn.apache.org/repos/asf/maven/
If you think it's better, I agree. But
how we do when we want to
release a plugin? All the plugins have to be stable at the same time?

components (which BTW could be used as the parent directory for
hosting components if/when we decide to move to using a
component-based architectire (OSGI, etc).
Yes, be carefull with the plugin with
dependencies inside the code
like the upload plugin. A solution, could be to change it to
component, and doing a plugin to access to the functions of this
component. Some plugins have dependencies between them also. for
exemple in the GELC project, some the plugins are depends on the
others. I think some plugins(actually on the core) are depend on
others.
An example of a module being only a component would be
the Store. An
example of a module being only a plugin would be the SVGPlugin. An
example of a module being both would be the FileUpload plugin.
Plugins/Components will need to be extended to add hooks to the XWiki
Action engine (currently based on struts). This would allow to
transform more code that the core depends on to plugins/components.
Maybe a module called "core-plugins" could make sense to package some
mandatory plugin for XWiki to actually work at least as a wiki.
Indeed we should prepare to implement a standard based component
architecture.
If it's possible to minimize the amount of jar that would be great,
especially for components.
All components would be included in the xwiki core distribution IMO.
3) Each
plugin build will result in a plugin jar and we add some or
all of those jars to the distributions. As there's currently no
online plugin downloading mechanisl we may need several
distributions: a minimal one without any plugin, one with "core"
plugins and one with all plugins. Or we could choose to have only 2:
one without plugins and one with all plugins.
I prefer the first solution, but with something a little bit
different, we distribute the core with the minimum required plugins,
and we create a repository with all the jar of the plugin (as ibilio
for maven), and a package with all the official plugins.
It could be a pain to have a jar for API and a jar for
implementation,
especially when XWiki core depends on that API. In this case it could
be better to leave it in the core.
The use of a core-plugins module could allow to reduce the amount of
jars.
Thanks
