    Default The package java.sql is not accessible

    Hello!

    After some time trying to make new project, but stuck in very beginning.

    The problem is that import does not see java library: The package java.sql is not accessible
    mysql-connector-java-8.0.18.jar is added through Build path configuration.

    Is there problem with mysql-connector-java-8.0.18.jar importing?

    Here is code:

    package newPackage;
    import java.sql.*;
     
     
    public class Piegades {
     
    public static void main(String[] args) throws Exception{
     
    		String url = "jdbc:mysql://localhost:3306/testdb";
    		String user = "root";
    		String password = "password";
     
    		Class.forName("com.mysql.cj.jdbc.Driver");
    		Connection con = DriverManager.getConnection(url, user, password);
    		System.out.println("Connection made");
    		con.close();
    		System.out.println("Connection closed!");
    	}
     
    }

    What IDE and JDK are you using? What is on the commandline when you compile the program?
    Why do you run the program if it has compiler errors?

    The code compiles without errors for me.

    Eclipse and JDK 12.

    I didn't run from commandline, but from Eclipse. I run it just to see more of error message. As I understand the problem is in fact that import java line is not seeing jova libraries...

    Sorry, I do not use Eclipse and don't know how to configure it.

    Try doing the compile from the commandline to see if it compiles there.

    I feel silly, but I solved problem my self. I made project from scrach and only thing I did another way – in New java project window in Project layout section this time instead of "Create separate folders for sources and class files" I used "Use project foler as root for sources and class files".
