Job Execution : where is retry cycle configuration?

I finally achieved what I wanted by adding this config :

	@Bean
public CamundaProcessEngineConfiguration camundaProcessEngineConfiguration() {
	return new CollWkfProcessEngineConfiguration();
}

and

@Configuration
public class MyProcessEngineConfiguration extends DefaultProcessEngineConfiguration {

//custom job retry value: 1
@Value("${camunda.bpm.job-execution.default-number-of-retries:1}")
private int defaultNumberOfRetries;

//custom failedJobRetryTimeCycle Retry once (R1), 1 minute between each try (PT1M)
@Value("${camunda.bpm.job-execution.failed-job-retry-time-cycle:R1/PT1M}")
private String failedJobRetryTimeCycle;

@Override
public void preInit(SpringProcessEngineConfiguration configuration) {
	super.preInit(configuration);
	configuration.setDefaultNumberOfRetries(defaultNumberOfRetries);
	configuration.setFailedJobRetryTimeCycle(failedJobRetryTimeCycle);
 }
}
