I have such a setup in cloudsmith/geppetto - a folder that is hidden (by
virtue of having a name starting with '.'). This project must have the
XtextNature set in order to be indexed, and it must be accessable (i.e.
open and "visible" (although hidden from the package explorer view, you
should be able to see it in the navigator view)).
Further, all projects that should have visibility into the hidden folder
must naturally have this declared - either via use of the Java Class
Path mechanism supported by Xtext, or via Project dependencies (also
supported by Xtext as an alternative). Or you need to come up with your
own scheme.
In cloudsmith/geppetto I choose to use Project dependencies (which I
configure using a build job that reads meta data embedded in the
projects). This works as a charm and required very little coding on my part.
Hope that helps. (The cloudsmith/geppetto code is at github). It deals
with other types of visibility issues as well (different types of
projects, preference based search paths, etc.). The project dependency
part should be reasonably general.
