For Remove Operation pre_commands are not started

Current Situation

• When user set the operation=remove with source_pre_commands, no pre_commands are started.
• Same pre_commands are working with operation, copy and move
• source_post_command is working as expected

How to reproduce

• See the attached YADE profile

  ;; Variant 01: Transfer file from localhost to remote server using SFTP
  [CopyLocalhost2RemoteServer]
  operation                           = remove
  file_spec                           = TRXDDLW[0-9]{4}.PDF$
  ;;
  source_protocol                     = local
  source_host                         = localhost
  source_dir                          = /home/jenkins/jade_test/out
  source_pre_command                  = echo "zip ${SourceFileName}_`date +%Y%m%d%H%M`.zip ${SourceFileName}" ; zip ${SourceFileName}_`date +%Y%m%d%H%M`.zip ${SourceFileName}
  source_post_command                 = touch ${SourceFileName}.post
  
  ;;
  target_host                         = homer.sos
  target_user                         = test
  target_protocol                     = SFTP
  target_ssh_auth_method              = password
  target_password                     = SUPER-PASSWORD
  target_dir                          = /home/test/inbound
  
  

Desired Behaviour

• YADE should start the source_pre_commands for remove operation.
