spring batch jobexplorer issue - spring-batch

Question

We are trying to run a spring batch which is failing with below issue.
My configs :
1) Spring boot
#ComponentScan(basePackages = { "some pkgs” })
#ImportResource("classpath:dataSource.xml")
#EnableAutoConfiguration(exclude = DataSourceTransactionManager.class)
public class CollateralReportGeneratorBootstrapper {
public static void main(String[] args) {
System.exit(SpringApplication.exit(SpringApplication.run(CollateralReportGeneratorBootstrapper.class, args)));
}
}
2) Batch
#Configuration
#EnableBatchProcessing
#ComponentScan(basePackages = { "some pkgs”})
public class ReportGenerator {
#Autowired
private JobBuilderFactory jobBuilderFactory;
#Autowired
private StepBuilderFactory stepBuilderFactory;
3) Dependencies : spring-batch-core, spring-batch-infrastructure, spring-boot-starter-batch
Please let me know if someone faced this issue or any idea about possible solutions !!
