JobStep 강의에서 childJob() 실행 질문

프로그램 변수 --job.name=parentjob1

   job:   
     names: ${job.name:NONE}
#      enabled: false

    @Bean

                .tasklet((a, b) ->{
                    log.info("Step2 확인");
                    return RepeatStatus.FINISHED;
                })
                .build();
    }

}

프로그램 변수로 인해서 parentJob1은 자동 실행 됩니다. 근데 childJob은 왜 자동 실행되는건가요?

(강의 코드와 동일하고 결과도 동일합니다)

Job 설정 파일을 볼 수 있을까요?
