The solution that works for me has two steps.

1. First step

   package com.student.mail;
   
   import java.util.Properties;
   
   import javax.mail.Authenticator;
   import javax.mail.Message;
   import javax.mail.MessagingException;
   import javax.mail.PasswordAuthentication;
   import javax.mail.Session;
   import javax.mail.Transport;
   import javax.mail.internet.InternetAddress;
   import javax.mail.internet.MimeMessage;
   
   /**

   public class GoogleMail {
       public static void main(String[] args) {
           Properties props = new Properties();
           props.put("mail.smtp.host", "smtp.gmail.com");
           props.put("mail.smtp.socketFactory.port", "465");
           props.put("mail.smtp.socketFactory.class",
               "javax.net.ssl.SSLSocketFactory");
           props.put("mail.smtp.auth", "true");
           props.put("mail.smtp.port", "465"); 
           Session session = Session.getDefaultInstance(props,
           new javax.mail.Authenticator() {
                               @Override
               protected PasswordAuthentication getPasswordAuthentication() {
                   return new PasswordAuthentication("conaderindicadores@gmail.com","Silueta95#");
               }
           });
   
       try {
   
           Message message = new MimeMessage(session);
           message.setFrom(new InternetAddress("conaderindicadores@gmail.com"));
           message.setRecipients(Message.RecipientType.TO,
                   InternetAddress.parse("netneillip@gmail.com"));
           message.setSubject("Testing Subject");
           message.setText("Test Mail");
   
           Transport.send(message);
   
           System.out.println("Done");
   
       } catch (MessagingException e) {
           throw new RuntimeException(e);
       }
   }
   
   }
