Parsing Email returning com.sun.mail.util.MailConnectException exception

Question

I have one requirement for parsing all email from one of gmail account.

My code is below

            Properties properties = new Properties();
            properties.put("mail.store.protocol", "pop3");
            Session session = Session.getDefaultInstance(properties, null);
            session.addProvider(new Provider(Provider.Type.STORE, "gimaps", "com.sun.mail.gimap.GmailSSLStore","Oracle","1.5.4"));
            GmailSSLStore store = (GmailSSLStore) session.getStore("gimaps");
            store.connect(user, password); <--- ERROR 
            GmailFolder folder = (GmailFolder) store.getFolder("INBOX");
            folder.open(Folder.READ_WRITE);

I have tried many ways by added all required properties mail.smtp.* but still i get below error

com.sun.mail.util.MailConnectException: Couldn't connect to host, port: imap.gmail.com, 993; timeout -1;
