Get IResource for java file knowning IClassFile derived from it? [message #260847]

Is there an easy way to lookup the original java file, as IResource
ideally, knowing the class file that was compiled from it? I'm trying to
indirectly use JDT's dependency analyzer to find out which java files were
compiled inside an Ant builder/custom task. I can get Eclipse pass the
incremental build resource delta to my Ant script which includes generated
class files, and I need to resolve them to their originating source files.
Perhaps there is a better way to solve this? Thanks.

There's no single API that would give you this.

Fair enough. Then it looks like the solution will be to search in the
source folders inside the corresponding packages. Does this sound like a
plausible approach?

Yep. As a first guess you could simply check whether there's a
corresponding *.java file / Compilation Unit and if not, do the search.
