Issue with my output file

[redking974]

Hi, I try to use sejda to merge several .pdf from a directory but I've got an issue because it tells me that output file is not defined, but I've added it into my command line.
C:\Users\Sebastien\Desktop\Elibray>"C:\Program Files (x86)\sejda-console\bin\sejda-console.bat" merge -d "C:\Users\Sebastien\Desktop\Elibrary\Pile\" -o "C:\Users\Sebastien\Desktop\Elibrary\FichierFinal.pdf"

Here's the logs :

Configuring Sejda 3.2.40
Starting execution with arguments: 'merge -d C:\Users\Sebastien\Desktop\Elibrary\Pile" -o C:\Users\Sebastien\Desktop\Elibrary\FichierFinal.pdf'
Java version: '1.8.0_131'
Option is mandatory: --output -o value : output file (required)
