我有一個SFTP問題(

Windows

WinSSHD).我嘗試用

Apache Commons VFS在一個文件夾中寫一個文件.在本地SFTP上我沒有上傳的問題,但在第二個SFTP上我總是得到以下錯誤.

FTP看起來像這樣：

我需要上傳到文件夾“alis”.奇怪的是它沒有User / Group和770權限.但是,使用FileZilla文件上傳工作正常(使用相同的登錄).

在文件夾“alis”上執行“manager.resolveFile()”(我嘗試上傳到此文件夾)并打印“.getType()”我獲取信息“文件”而不是預期的“文件夾”.

有沒有人知道為什么VFS會將文件夾識別為文件或為什么上傳不起作用？

將文件上載到SFTP時的例外情況：

Exception in thread "main" java.lang.RuntimeException: org.apache.commons.vfs2.FileSystemException: Could not copy "file:///D:/Test/test.txt" to "sftp://user:***@host/.../alis/test.txt".
