Comment puis-je corriger ClassNotFoundException: com.sun.mail.util.MailLogger?

Question

Je veux envoyer un email, mon code est ci-dessous

public static void main(String[] args) { 

    final String username = "emailId@gmail.com"; 
    final String password = "password"; 

    Properties props = new Properties(); 
    props.put("mail.smtp.auth", "true"); 
    props.put("mail.smtp.starttls.enable", "true"); 
    props.put("mail.smtp.host", "smtp.gmail.com"); 
    props.put("mail.smtp.port", "587"); 

    Session session = Session.getInstance(props, 
     new javax.mail.Authenticator() { 
     protected PasswordAuthentication getPasswordAuthentication() { 
      return new PasswordAuthentication(username, password); 
     } 
     }); 

    try { 

     Message message = new MimeMessage(session); 
     message.setFrom(new InternetAddress("from-email@gmail.com")); 
     message.setRecipients(Message.RecipientType.TO, 
      InternetAddress.parse("email1@google.com")); 
     message.setSubject("Testing Subject"); 
     message.setText("Dear Mail Crawler," 
      + "\n\n No spam to my email, please!"); 

     Transport.send(message); 

     System.out.println("Done"); 

    } catch (MessagingException e) { 
     throw new RuntimeException(e); 
    } 
}
