线程“main”中的异常java.lang.NoClassDefFoundError：org/sqlite/NativeDB

我正在尝试在mac上运行一个简单的sqlite示例.我很确定该代码在 Windows上运行良好.但不是在Mac上.如果有人能帮助我,我真的很感激.

代码在Eclipse中运行.我添加了sqlite-jdbc4-3.8.2-SNAPSHOT.jar作为内部和&项目中的外部jar.

public class Test1 {

  private static Connection c;
  private static String filepath = "/Users/zerocraft/Documents/workspace/sql_test/";
  private static String sql;
  private static Statement query;


  public static void main(String[] args) {
          System.out.println("START");
          try{

            Class.forName("org.sqlite.JDBC");
            System.out.println("START2");

            c = DriverManager.getConnection("jdbc:sqlite:"+filepath+"projone.db");
            System.out.println("START3");

            }

            catch(Exception e){
                e.printStackTrace();
            }

                 sql =  "INSERT INTO table(date,time,client_id,run_id,latitude," +
                        "longitude,bearing,speed,altitude,sensor_id,sensor_type," +
                        "sensor_value,attribute)"
                + "VALUES ('A','B','C','D',1,2,3,4,'E','F','G','H')";


                try{
                query = c.createStatement();

                 query.executeUpdate(sql);
                 query.close();
                }
                catch(sqlException el){el.printStackTrace();}
        }   
   }

安慰 ##

解决方法

最后,我想出了如何让它发挥作用.我尝试了另一个jar,它(sqlite-jdbc-3.7.2.jar)适用于Mac.看来是sqlite-jdbc4-3.8.2-SNAPSHOT.jar. @ddevienne,也许3.8.2不支持Mac OS.
