Dependency management during build process [message #758540]

I have defined a grammar in which top level elements are "Entities" (so, one entity will be contained in one file). Such an entity can reference other entities (which are of course defined in separate files). If one of these referenced entities change, I would like to regenerate the code of the modified entity AND of the entity which is referencing the modified entity.
This would require that the Xtext builder somehow follows the cross-links and add those referenced entities to the "to be built" list.

How is it possible to achieve something like that ?

If your Entities are exported/exposed to the Builder Index through a qualified name, this should be pretty much automagical.

Thanks for the reply.
I don't understand your answer: my entities are top level elements (each in its own file) and they reference each other using their name.
How can I "export" them to the builder through qualified name ? In my workflow file to generate my grammar I have:

fragment = exporting.QualifiedNamesFragment {}

But still, if I modify an entity file, other Entities which are referencing this Entity are not regenerated.
