It was resulting in weird situations where the tool would dump an error message and stack but not quit, or would fail hard but then just hang. Instead, specifically catch errors you expect. As an example of this, there's one error we expect from the DartDependencySetBuilder, so we catch that one, turn it into a dedicated exception class, then in the caller catch that specific exception.
