Hi

I think you should use the buckminster forum eclipse.tools.buckminster
for user related questions (I guess this forum is for developer related
questions :)

Anyway, If you run such ant task from buckminster, then the mwe2
launcher has to be installed in buckminster itself; so, when installing
buckminster, you should also install the feature
org.eclipse.emf.mwe2.launcher.feature.group which can be found in this
update site
http://download.eclipse.org/modeling/emft/mwe/updates/releases/2.7.1/ or
in the Xtext composite update site.

Hope this helps
	Lorenzo
