Hello. I looked through the problems associated with this topic, but did not find the answer. Perhaps doing something wrong. The essence of the problem: I am trying to create an elementary connection to the MySQL database in Eclipse using java Actually, here is the code:
public class DB { public static void main(String[] args) { try { Class.forName("com.mysql.cj.jdbc.Driver"); System.out.println("Driver loading success!"); //у MySQL обязательно есть системная база, //к ней и будем создавать соединение. String url = "jdbc:mysql://localhost/mysql?autoReconnect=true&useSSL=false"; String name = "root"; String password = "root"; try { Connection con = DriverManager.getConnection(url, name, password); System.out.println("Connected."); con.close(); System.out.println("Disconnected."); } catch (SQLException e) { e.printStackTrace(); } } catch (ClassNotFoundException e) { e.printStackTrace(); } } } And in return I get:
Driver loading success!
java.sql.SQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up. at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:108) at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:95) at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:87) at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:61) at com.mysql.cj.jdbc.exceptions.SQLError.createSQLException(SQLError.java:71) at com.mysql.cj.jdbc.ConnectionImpl.connectWithRetries(ConnectionImpl.java:932) at com.mysql.cj.jdbc.ConnectionImpl.createNewIO(ConnectionImpl.java:857) at com.mysql.cj.jdbc.ConnectionImpl.<init>(ConnectionImpl.java:444) at com.mysql.cj.jdbc.ConnectionImpl.getInstance(ConnectionImpl.java:230) at com.mysql.cj.jdbc.NonRegisteringDriver.connect(NonRegisteringDriver.java:226) at java.sql.DriverManager.getConnection(Unknown Source) at java.sql.DriverManager.getConnection(Unknown Source) at telegrambot.DB.main(DB.java:41) Caused by: com.mysql.cj.exceptions.InvalidConnectionAttributeException: The server time zone value 'RTZ 2 (????)' is unrecognized or represents more than one time zone.

I downloaded various versions of JDBC Connector from 5.0 to 8.0.11 - it did not help I tried to add a new version of the driver in Eclipse, but it opposes me (I attach a screenshot) 
If someone tells you how to add a driver of newer versions here, I will be very grateful!
I also tried in linux to connect to an already used and working database from a Django project with exactly the correct username and password (because one of the reasons for this error could be an incorrect username and password)
Actually, everything seems to be. I killed the whole day to solve this problem and no longer know what to do. Can someone tell me?
