Error in building LibreOffice with Cygwin

I faced a missing package error while building LibreOffice with cygwin.
LibreOffice version: 6.0.1.1
MSVC: 2017
autogen.sh works successfully, but an error occurred when building it.
It’s an error of missing journey-1.0.tar.gz.
I searched at Google, but I cannot find any news about this.
Please help me, how can I resolve this issue. Thank you in advance.

Stop.

Wow, building 6.0.1.1. Why would anyone want to build that specific version! Not 6.0.7.3 (the last one on 6.0 series, even if one wanted old 6.0 for some unclear reason)!

Anyway, see @gabix’s advise. Also you may try to ask at #libreoffice-dev on FreeNode.
