Skript works from CMD but not from CI tool (Jenkins)

This script is called from a BAT file. If I execute the BAT manually from CMD, everything works as expected.

If I execute the BAT through Jenkins it stops after pretranslating = doesn't update the translator files (*tbulic).

Any clues how to debug this?

Greetings,
