retepXMPP - Schemas
· This part of the project contains the core api, xml schemas for each
supported xmpp protocol and the jaxb generated code.
Because this section rarely changes (i.e. when a new protocol is added
or when an existing protocol is updated by the XMPP Standards Foundation
its usually not required to actually build from this directory but
allow maven to retrieve the pre-built artifacts instead.
Doing this will save you a lot of time as there are over 100 modules
within this part of the project.
