Transfer using Jump-Host will fail for "From Internet" when 0 files found

Current Situation

• If YADE is configured to use the "From Internet" direction (Source on another network -> Jump -> Target) and the selection from the Source on another network returns no files, the transfer will fail with the exception:

   com.sos.commons.vfs.exceptions.ProviderException: [selectFiles][Jump][<jump_dir>/yade-dmz-<uuid>/data]net.schmizz.sshj.sftp.SFTPException: No such file

• Cause
  • YADE creates the following subfolders on the Jump-Host in the YADE temporary working directory:
    • config
      • This subfolder is automatically created on each run and serves as storage for temporary configurations, e.g., settings.xml.
    • data
      • This subfolder contains the transferred files and is automatically created only when at least one file is available for transfer.
      • If no files are found, the exception described above occurs because the data directory does not exist.

Desired Behavior

• No errors should occur when the file selection returns 0 files.
• To achieve this, all required transfer subfolders (config, data) should be created automatically when a transfer starts, regardless of whether the later file selection returns files.

Patch

• Use the cumulative patch provided with YADE-642.
