title: Import XXX cannot be resolved for Java SE standard classes
body: <p>I use Eclipse and turns out I have a bunch of import <em>*</em> not resolved errors.</p>
  
  <pre><code>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;
  </code></pre>
  
  <p>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.</p>
