Can eclipse prevent you from using particular classes?

Question

For example,

1. I don't want to use org.testng.v6.Maps, (I want com.google.common.collect.Maps)
2. I don't want to use org.hibernate.mapping.List, (I want java.util.List like everyone else!)

Is there a way to tell Eclipse not to suggest these in the autocomplete box?

Answer 1

Yup - I have exactly this problem at work for a few classes too.

Preferences -> Java -> Appearance -> Type Filters.
