如何从eclipse项目引用jar？

我有一些代码从健身网站复制：如何从eclipse项目引用jar？

package fixtures; 

import static fitnesse.util.ListUtility.list; //fitnesse.util can not be resolved 
import static util.ListUtility.list; //this one resolves but is no help in getting list to work below 


import java.util.Date; 
import java.util.List; 

public class EmployeesHiredBefore { 
    private Date date; 

    public EmployeesHiredBefore(Date date) { 
    this.date = date; 
    } 

    public void table(List<List<String>> table) { 
    //optional function 
    } 

    public List<Object> query() { 

    return 
     list(
     list(
      list("employee number", "1429"), 
      list("first name", "Bob"), 
      list("last name", "Martin"), 
      list("hire date", "10-Oct-1974") 
     ), 
     list(
      list("employee number", "8832"), 
      list("first name", "James"), 
      list("last name", "Grenning"), 
      list("hire date", "15-Dec-1979") 
     ) 
    ); 
    } 
}

我已经加入到建立与路径增加其fitnesse.jar内容的外部jar包括util/ListUtility.class

任何人都知道如何引用这个瓶子？
