Не могу создать новый локальный рабочий файл во время использования файла из SFTP

Question

Не могу создать новый локальный рабочий файл во время использования файла из SFTP

Я использую верблюд версии 2.15.2

У меня есть конечная точка

final String endpoint = "sftp://myUsername@$myHost:22/test-dir/?connectTimeout=5000&password=MySuperSecretPassword&ignoreFileNotFoundOrPermissionError=false&fileName=FABT_Index_DE.xls&delete=false&localWorkDirectory=/test-dir/

и я делаю следующее, чтобы получить названный файл из SFTP

  @Autowired
  private CamelContext camelContext;

  ...some Stuff...

  private Exchange fetchFile(final String enpoint, final long timeout) {
        final ConsumerTemplate consumer = camelContext.createConsumerTemplate();
        return consumer.receive(endpoint, timeout);
  }

Когда я запускаю свое приложение на моем компьютере (OS = Windows) ... все в порядке. Файл извлекается из SFTP. Я подумал, что было бы неплохо проверить, работает ли приложение на другом компьютере... поэтому я скопировал свой jar-файл в SFTP (OS = linux) и запустил его там... (это та же машина, где находится файл размещен)

Теперь я получаю следующее исключение:

Может кто-нибудь сказать мне, почему я получаю это исключение - вместо получения файла из SFTP?

Я узнал следующее:

я использовал для конечной точки и локального рабочего каталога ту же строку test-dir, После некоторых экспериментов кажется, что для определения конечной точки

final String endpoint = "sftp://myUsername@$myHost:22/test-dir/?connect ...

test-dir это относительный путь. например, этот каталог находится по адресу /vol/usr/home/MyTestUser/test-dir а также /vol/usr/home/myUsername/ это домашний каталог SFTP-пользователя (или каталог, который вы получаете при входе в систему через ssh) - можно определить конечную точку с помощью /test-dir/

Но для варианта localWorkDirectory

final String endpoint = " ... &localWorkDirectory=/test-dir/ ..."

кажется test-dir это абсолютный путь. Поскольку я пытаюсь запустить приложение на SFTP, я не получил разрешения на запись в абсолютный каталог /test-dir/ поэтому я изменил этот каталог на /vol/usr/home/myUsername/MyTempDirectory/ и добавьте опцию &stepwise=false, И теперь это работает. Конечная точка сейчас:

final String endpoint = "sftp://myUsername@myHost:22/test-dir/connectTimeout=5000&password=MySuperSecretPassword&ignoreFileNotFoundOrPermissionError=false&fileName=FABT_Index_DE.xls&delete=false&localWorkDirectory=/vol/usr/home/myUsername/MyTempDirectory/&stepwise=false";

Возможно, кто-то сможет уточнить это более точно...
