尝试连接到亚马逊红移驱动程序时出现“Caused by: java.lang.ClassNotFoundException: java.sql.SQLException”

Question

下面是POM依赖

<dependency>
            <groupId>com.amazon.redshift</groupId>
            <artifactId>redshift-jdbc42</artifactId>
            <version>2.1.0.28</version>
        </dependency>

数据库连接代码包含在以下路径中

src -> main -> utils -> DatabaseConnection.java

import java.sql.Driver;
import java.util.Properties;
import java.sql.*;
public class DatabaseConnection {
    Logger logger = LoggerFactory.getLogger(DatabaseConnection.class);
    Connection connection = null;
   Properties props  = new Properties();

    public  void getDataBaseConnection() {

        try {
            Class.forName("com.amazon.redshift.jdbc42.Driver");
            logger.info("Connecting to database...");
            String jdbcUrl = "jdbc:redshift://endpoint:port/dbname";
            String dbUsername = "username";
            String dbPassword = "password";
            jdbcUrl = jdbcUrl + "?AccessKeyID=" + dbUsername + "&SecretAccessKey=" + dbPassword
                    + "&DbUser=admin&ssl=true&tcpKeepAlive=true";
            props.setProperty("ssl", "true");
            props.setProperty("user", dbUsername);
            props.setProperty("password", dbPassword);
            connection = DriverManager.getConnection(jdbcUrl, props);
            if (connection != null) {
                logger.info("Connected to the database!");
            } else {
                logger.info("Failed to make connection!");
            }
        } catch (Exception e) {
            e.printStackTrace();
        }


    }
}

并在testng文件的以下路径中调用上面的代码

src->测试->java->测试->名称->sample_test.java

import utils.DatabaseConnection;
public class sample_test extends TestBase {

    DatabaseConnection dbconn  = new DatabaseConnection();

@Test
public void db_test(){
        dbconn.getDataBaseConnection();
    }
}

执行上述操作后，出现以下错误
