Getting job id as an input

Hello,

I would like to get the job id (such as #2594) of the current teamcity job as an input to my script. I tried:

if [ $? != 0 ]; then
    python ./src/scripts/python/utils/store_test_artifacts.py --buildId %system.build.number%
fi

But this leads to the error: 

There are no compatible agents which can run this build.

Implicit requirements:

 system.teamcity.build.id defined in Build step: Setup

How can I pass the jobID shown in teamcity to my script?

Kind regards

Matthias
