I can help with publishing Hudson build results to the Eclipse download page. A while ago I updated five of my Eclipse modeling projects to publish their builds from their HIPP instance to the downloads page.
Cheers...

Plus, publishing Hudson build results to the Eclipse download page. Today they are just pushed to repo.eclipse.org which is not a suitable place for end users to consume from.

Bad news:
It turned out my previous test builds were not being minified correctly.
r.js has an option ("skipDirOptimize") that I was using to minify only the pages that Orion needs at runtime, and skip other .js files in the build directory. But for the PDE build running at build.eclipse.org, this inexplicably causes the minifier to skip all the files and minify nothing. I could not reproduce the problem in Maven builds.
The only workaround I could find was to run the minifier on all 602 js files in the build folder, even though only about 8% of those are ultimately needed at runtime after dependencies have been inlined. Once the PDE build is decommissioned -- hopefully soon -- we can remove this workaround and the builds will be fast again.
The build time is now 40 minutes.

I've released some changes to Orion's build-time JS minification. The rationale is twofold:
1. Reduce build times [1].
2. Reduce duplicated logic across various builds of Orion (Maven, PDE, Node, etc), to make it easier for developers to get new pages minified without breaking things. [2]After some initial problems, builds seem to be working OK again. (If you notice any problems with build output or minification, please open a bug and assign it to me.)
Here's a summary of the results:
1. Build times
Proper use of r.js has reduced the minification time for Orion's client code from 68 minutes to 12 minutes [3][4]. As the build scripts are now shared, the PDE build has seen similar improvements. This gives us total build times of ~21 minutes (PDE) and ~28 minutes (Hudson
, orion-client + orion-server).
2. Build maintenance
>From now on, the only file developers should normally have to maintain is this one in the client repo:
releng\org.eclipse.orion.client.releng\builder\scripts\orion.build.js.
This is the RequireJS build file used to minify the Orion client UI. It contains a few additional parameters that are not standard RequireJS.
See below for Orion-developer-oriented details about the client build.
Adding a new module to the client build
There's just one step:
1. Add an entry to the modules section of orion.build.js.
Every entry needs a name property and a bundle, which tells the builder which bundle the minified module should be copied back into. For example, here is the Git Commit page's entry:
{ name: "git/git-commit",
bundle: "${buildDirectory}/bundles/org.eclipse.orion.client.git"
},
^ Ant-style property replacement is supported, but ${buildDirectory} is all you should use there. The PDE, Hudson, and Node builds all share orion.build.js, so your new module will be correctly built everywhere.
Adding a new client bundle to the JS build
1. Add an entry to the bundles section of orion.build.js.
2. If your bundle contains any JSDocs, add an entry to the jsdocs section of orion.build.js.
3. Add module entries for any of the bundle's modules you want minified (see previous section).
4. Add an entry to the <modules> section of the client repo's top-level pom.xml to ensure that the Maven builder finds your bundle.
Building stand-alone features (like the standalone Orion editor)
Right now these are still handled separately by the build script. You must add logic to orion.mini.xml that invokes r.js, passing the build file for your feature. Use the standalone editor build as a reference.
Thanks
