ci-management/jjb/appc/appc-csit.yaml has the following:

trigger_jobs: '{project-name}-{stream}-release-java-daily-checkstyle'

However, no such jobs exist for master (or any other stream). This trigger should be removed to avoid confusion.

Note that adding an existing job to trigger this (for example some docker image-producing job) is currently not recommended as the CSIT is scheduled to run daily anyway and real trigger would mostly just add load to Jenkins without any additional real value.
