Java郵件Api，從Gmail中刪除郵件

由於測試的原因，我希望每天都有一個電子郵件帳戶爲空，我有這個代碼，但並沒有刪除郵件。Java郵件Api，從Gmail中刪除郵件

public class EmailService { 

    private String HOST = "imap.gmail.com"; 
    private String USERNAME = "[email protected]"; 
    private String PASSWORD = "pass"; 
    private Properties properties; 
    private Store store; 
    private Folder inbox; 

    public EmailService() throws MessagingException { 
    this.properties = new Properties(); 
    this.properties.put("mail.imap.host", HOST); 
    this.properties.put("mail.imap.port", "993"); 
    this.properties.put("mail.imap.starttls.enable", "true"); 
    } 

    public void openEmailSession() throws MessagingException, InterruptedException { 
    Session emailSession = Session.getInstance(this.properties); 
    emailSession.setDebug(true); 
    this.store = emailSession.getStore("imaps"); 
    this.store.connect(HOST, USERNAME, PASSWORD); 

    this.inbox = this.store.getFolder("INBOX"); 
    this.inbox.open(Folder.READ_WRITE); 
    } 

    public void closeEmailSession() throws MessagingException, IOException { 
    this.inbox.close(true); 
    this.store.close(); 
    } 

    public Message[] getUserMessages() throws MessagingException, IOException { 
    Message[] messages = this.inbox.getMessages(); 
    return messages; 
    } 

    public void cleanInbox() throws IOException, MessagingException { 
    Message[] messages = this.getUserMessages(); 
    for (Message message :messages) { 
     message.setFlag(Flags.Flag.DELETED, true); 
    } 
    } 
}

當我執行：

emailService.openEmailSession(); 
emailService.cleanInbox(); 
emailService.closeEmailSession();

的郵件從收件消失，但後來我點擊所有郵件和電子郵件依然存在，垃圾桶是空的。我不明白髮生了什麼事。

在在Gmail設置「轉發和POP/IMAP」我已經嘗試過autoexpunge開/關和

「當被刪除，而從最後IMAP資料夾刪除消息標記爲」三個選項，但沒有什麼變化......我失蹤了什麼？

[JavaMail調試輸出]（http://www.oracle.com/technetwork/java/javamail/faq/index.html#debug）顯示什麼？ –

我用調試輸出更新了原來的問題。 – FranAguiar

當談到IMAP時，Gmail有點「奇怪」。據我瞭解，刪除的郵件將被移至垃圾箱。要真正擺脫這個信息，你必須從垃圾桶中刪除它。如果你看「所有郵件」，郵件將在那裏，因爲，它是**所有郵件**！如果他們在刪除後沒有從INBOX中消失，那是一個更大的問題。 –

我找到了一個替代的解決方案，是不是最適合我的目的（詹金斯集成），但它適用於現在。

是一個非常簡單的功能在谷歌腳本中，你可以選擇你的電子郵件和安排功能，只要你想。

https://www.google.com/script/start/

function cleanInbox() { 
    var threads = GmailApp.search('label:inbox'); 
    for (var i = 0; i < threads.length; i++) { 
    threads[i].moveToTrash(); 
    } 
}

你必須首先將郵件複製到該文件夾[Gmail]/Trash，這將導致其從當前文件夾被立即清除。然後你必須打開[Gmail]/Trash並刪除該消息。這將使信息消失。

我將此信息添加到JavaMail FAQ。
