Answer 1

In eclipse if you right click on your Project in the Package Explorer, then go to properties -> Java Compiler -> Errors/Warnings. You can then manually change which compiler findings appear as warnings/errors/ignored etc...

Answer 2

I will update @Matthew Ertel's answer to April, 2021.

Menu Window > Preferences > Java > Compiler > Error/Warnings.
