We now have a build that can do that for the "core" bits of WikiText using the maven-release-plugin.
My current plan is to do a Mylyn Docs release per the EDP, but only release the Mylyn WikiText "core" bits. The rest of Mylyn Docs including the WikiText UI bits would release in conjunction with all of Mylyn per our existing process.
This change in process will enable consumers outside of the Eclipse ecosystem to consume WikiText, and will also enable us to release more frequently.
Let me know if you have any feedback, positive or otherwise!
