Error occur when i creating spring batch multiple JobBuild - spring

Question

I'm using kotlin, spring boot 3.0.1 and batch .
I create two of job/step configuration. but when i build the project, i've saw the below errors.
I'm asking a question because it's hard to change the previous batch example to the latest version. Has anyone solved this problem?
Strangely enough, if you take one job out on config, it can running it.

Error starting ApplicationContext. To display the condition evaluation report re-run your application with 'debug' enabled.

The issue very clear from logs.

If only one job is present in Spring Context then Spring run that job by default on startup but If multiple jobs are present in Spring Context then we need to tell Spring which job to run on startup.
So you can specify this property in application.properties file and try again.
spring.batch.job.name=singleStepJob
or
spring.batch.job.name=multipleStepJob
or you can disable running job on startup by this property and run the job programmatically using JobLauncher.
spring.batch.job.enabled=false
How to run job programmatically?
public class JobLauncherService {
private final JobLauncher jobLauncher;
private final Job job;
#Autowired
public JobLauncherService(JobLauncher jobLauncher, #Qualifier("multipleStepJob") Job job) {
this.jobLauncher = jobLauncher;
this.job = job;
}
public void runJob() {
try {
final JobExecution jobExecution = jobLauncher.run(job, new JobParameters());
System.out.println("Job Status : " + jobExecution.getStatus());
System.out.println("Job completed");
} catch (Exception e) {
e.printStackTrace();
System.out.println("Job failed");
}
}
}
