There are two options
- Bundle subversion plugin in the war and install SVNKit
dynamically on the first run.
- Don't bundle the subversion plugin in the war (keep the source at
Github and release it from there). Give an opportunity to the user
to install it at first run along with few others such as JFreechart
or JNA if needed.
Option 1 is complicated.
- Plugin manager extracts the plugin from war and creates the
folder <HUDSON-HOME>/plugins/subversion, when hudson first
starts.
- We need to install svnkit under
<HUDSON-HOME>/plugins/subversion/WEB-INF/lib
- But when Plugin manager extract the plugin, it also loads the
plugin and thus would break hudson
- Also since we build subversion plugin with out svnkit, if there is
a upgrade, that would also break. Because the plugin folder is wiped
out first along with svnkit.
IMO, the easiest option is option 2.

Folks
In relation to the CQ request for SVNKit 1.3.7 (CQ
6184). We have hit a bit of a roadblock in that we can't
distribute SVNKit from Eclipse.org (see extract below)
Given that SVN is very much part of Hudson Core I don't think that
we want to push it out onto the Plug-ins site (although that's an
option in the short term). How feasible is the self-bootstrapping
idea where we pull the JAR dynamically on first run?

IP review of previous versions of SVNKit have determined that
there are "difficulties associated with licensing and pedigree".
The TMate license has been determined to be incompatible with
the EPL; this is--essentially--a full stop with respect to any
effort to distribute this library from Eclipse.
There is potential to have this library declared as a
"WORKSWITH" on the basis that Hudson works just fine without
this library, but has enhanced functionality if the library is
present. The wrinkle is that the library cannot be distributed
from eclipse.org (i.e. it cannot exist in our code repositories,
or download server). It may be used to compile as part of a
build on our build server as the build server is not accessible
to the general public.
FWIW, the Subversive project uses SVNKit in this manner. The
first time you use Subversive, they open a dialog box that
invites the user to download SVNKit (among other options); at
that point the user is required to accept the license
explicitly.
Do you want to move forward with this as a WORKSWITH? Let me
know if you have other questions.
