Need maven based javadoc build artifact
Currently, none of the release artifacts include javadocs, which we need at least for the website.
The PR at https://github.com/igniterealtime/Openfire/pull/1245 now generates the sources JAR file (e.g. xmppserver/target/xmppserver-4.3.0-SNAPSHOT-sources.jar)
They may also be uploaded to the Maven repo - but not sure how they would then find themselves on the web site.
