Hi all, I now have a development build of the oxygen-tei add-on working. You can subscribe from here: http://teijenkins.hcmc.uvic.ca/job/oxygen-tei/lastSuccessfulBuild/artifact/o... If you're brave enough to try it, uninstall the regular version of the add-on before installing this one. I can also confirm that James was right: you can provide access to multiple versions of the plugin, allowing people to roll back to a previous version if something breaks, by providing multiple xt:extension elements in the updateSite.oxygen file. This seems to be working well with the URL above: if, when you're subscribing to the plugin (Help / Install New Add-Ons) you uncheck the "Show only the latest versions of the add-ons", you'll see there are three versions available. I have it set up so we'll keep the last ten versions available. I've subscribed myself, so I should be able to see if anything goes wrong. If you do test it, be aware that if you have transformation scenarios (for instance) that depend on the absolute location of the TEI extension framework, those paths will no longer work; Oxygen stores the add-on data in a path which includes a modified version of the URL of the updateSite.oxygen file. It's easy to change back to the standard TEI release, though. A new version of the plugin will be built and "released" every time the Stylesheets or P5 are rebuilt; the former triggers the latter, so the overall process takes quite a while, but the build of the oxygen-tei plugin itself takes only a few seconds. I'm copying Sebastian on this because my Jenkins is still reporting build failures and successes to him, as the Oxford one does to me, and I want to confirm that this should continue (or if it shouldn't, then what should happen instead). I'd also like to get this setup working on the Oxford Jenkins so we have some redundancy. The next step is to create some tests we can run in Oxygen to check core functionality of the add-on. I envisage this as an Oxygen project with a bunch of sample files that are transformed or otherwise manipulated and the results checked. These files would presumably live in the oxygen-tei repo. Cheers, Martin
