[Springframework-developer] build and distribution processes

SourceForge Headquarters 1320 Columbia Street Suite 310 San Diego, CA 92101 +1 (858) 422-6466

It seems to me that the current process as Juergen describes it is the 
correct one. It makes sense to distribute the sample sources with the 
spring jars. I don't see any need to distribute war files as developers 
who are not just browsing are going to build them themselves. If they 
just want to see them in action and browse the accompanying tutorial 
documentation, we should have the samples running on the website.

The fact that the samples are becoming part of the framework means they 
will need good tests that are run as part of any production release. 
Petclinic definitely needs work in this area.

I agree that the website should be high priority. I won't say much about 
what's there because I see it is changing a lot right now, though it 
would be nice to see the themes sample deployed there. As for myself, 
I'm going stop tweaking Petclinic code for now and focus on tutorial 
text :-( . I think we at a bare minimum need design notes and 
installation/setup instructions for Wednesday.

They do not require Spring's main build.xml but just its prebuilt jars and some of the third-party libs in the main lib directory. With the current layout, this works both with a Spring CVS snapshot and a release distribution.

That might still be an acceptable tradeoff for a release distribution: extra 2 MB for pregenerated wars of both samples. If a majority votes for it, fine - for a release.

We're talking about the evolving framework here, with frequent changes to be expected. And CVS snapshot users have to be familar with Ant anyway.

>BTW, Rod: We are running out of time in terms of getting a release plus a proper website out on Wednesday. But we shouldn't delay it, a release is _really_ important now. Unfortunately, a release with the current www.springframework.org website would leave a shallow first impression, so I consider a nice-looking website important too. I'm not getting this straight currently. What do you suggest?
