Hi Patrick,

the easiest way is to package a complete distribution for your clients,
but this may be somewhat oversized depending on the number of your
plugins and their dependencies. Another solution is a feature, that
contains the Xtext runtime feature. Clients who install your feature
will automatically get the Xtext runtime layer without all this UI stuff
like "new Xtext project".

I think their are various tutorials out there about how to package
plugins into a product or whatever you like. At the moment, there is no
step by step tutorial available as part of the Xtext documentation, but
we are working on something like this. See here:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=279477

The WorkflowAntTask is somewhat complicated because it does not use the
classloader from the environment (even if you can pass it). Therefore
it's most likely that you'll have to wait for the 0.8.0M2 of EMFT before
you can use it in an OSGi environment, as we changed the packaging
recently to ease the usage of this task from the very same OSGi
instance. Maybe someone from the EMFT newsgroup can jump in and explain
this a little bit more detailled? The short answer is most probably: If
you can avoid to use this AntTask from within the OSGi environment, you
should try to do so.

Hope that helps,
Sebastian
