java.util.Scanner cannot be resolved [duplicate]

Question

I use Eclipse and turns out I have a bunch of import * not resolved errors.

import java.sql.Date;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;
import java.sql.Timestamp;
import java.text.SimpleDateFormat;
import java.util.ArrayList;
import java.util.Calendar;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import java.util.Map.Entry;

All of the above have the same error. I checked my java version it is 1.7.0 open jdk. I updated Java Home and the JRE library to use. Its still not working. Note: I imported the code repository from bibucket via the mercurial plugin itself.
