Java mail iCloud mail connect to IMAP server

Question

I am trying to connect with iCloud mail using Java app. I want to read mails from iCloud IMAP mail server using user credentials. But it does not works. Below code snippet worked for Gmail, Yahoo, Outlook, but not working for iCloud:

public void connectToIMAP(final User user, MailSettings settings) {     
    ICloudSettings iCloud = (ICloudSettings) settings;

    properties = System.getProperties();
    properties.setProperty("mail.store.protocol", iCloud.imap.protocol);
    properties.setProperty("mail.imap.starttls.enable", "true");
    properties.setProperty("mail.imap.debug", "true");
    try {
        session = Session.getInstance(properties);
        session.setDebug(true);         
        store = session.getStore();         
        store.connect(iCloud.imap.host, iCloud.imap.port, user.getEmail(), user.getPassword());
        folder = store.getFolder(MailSettings.INBOX);
        folder.open(Folder.READ_ONLY);          
    } catch (Exception e) {
        e.printStackTrace();
    }
}

public ICloudSettings() {
    imap.host = "imap.mail.me.com";
    imap.port = 993;
    imap.protocol = "imaps";
}

Debug info is:

It didn't like your credentials. Double check your username and password. Make sure they work in a standard IMAP client. — Max
@Max Credentials are correct, I verified my credentials on browser and it works perfectly. — user2618875

Hi I'm also connecting to iCloud via IMAP, but not with java mail. I'm using piece of code from K9 mail client, available at github. I find out that accessing IMAP does not work when you have 2 factor authorization turned on for your icloud account. Second scenario when I get similar message to you (Authentication failed) is when I use email address different then @icloud.com one. For example I set up my apple id with my gmail account, and created @icloud.com alias. I cannot access IMAP with gmail address as username, but there is no problem when I use @icloud.com alias.
