Builders are more deterministic: you know when they're going to run.  My 
personal rule of thumb now is that resource change listeners are great for 
doing things like updating views, or perhaps reporting errors as in your 
case, but lousy for anything that generates further artifacts.  If you must 
use a resource change listener, make sure it's very smart about not doing 
unnecessary work, e.g., don't modify files just to update a timestamp.

At my company we've had tremendous headaches with things like endless build 
loops caused when a builder generates a file, that triggers a resource 
change listener, that produces a new file, that triggers a build, etc.
