I have a lot of this warnings in project and I would like to turn it off. I'm not interested in removing those imports, so please don't tell me how to do it.
I'm using eclipse 3.4.2.
To change for the entire workspace:
Window > Preferences > Java > Compiler > Errors/Warnings > Unused Import > Ignore.
To override workspace settings for a single project:
Project > Properties > Java Compiler > Errors/Warnings > Unused Import > Ignore.
