I have two jobs: CI (multibranch pipeline job) and Deploy (pipeline job).

CI triggers Deploy via pipeline build step:

build job: 'Deploy', parameters: [
    string(name: 'deployBranch', value: 'develop'),
    string(name: 'deployEnv', value: 'dev')
]

when

CI job is run by default using jenkins user with configured default home directory /var/jenkins_home. But triggered Deploy job is run by the same jenkins user BUT in directory /home/jenkins. Of course, there is no any workspace folder there and Deploy job fails.

When I rerun Deploy job manually it is run with correct home directory /var/jenkins_home and * successfully * deploys my artifacts.

Why is home directory changed? And how to prevent it or force the correct one?
