AbstractDistributeOnceElasticJobListener is wrong. why ?**
exception like this:
org.springframework.beans.factory.BeanCreationException: Error creating bean
with name
'org.apache.shardingsphere.elasticjob.lite.spring.boot.job.ElasticJobBootstrapConfiguration':
Invocation of init method failed; nested exception is
java.util.ServiceConfigurationError:
