[cdt-dev] Using the CDT API from a Java application, rather than an Ecli

["Marica M" <marica.marius@xxxxxxxxx>]

I'm trying to use the CDT API from an ordinary Java application, and not
from an Eclipse plug-in.

Generally speaking, is that possible?


When I try to run the below program, I get an exception regarding a "closed
workspace".
Is there another way for getting the AST, that doesn't involve Eclipse?
