There was an error in adding redis after springboot integrated elasticsearch.

  java, question

spring boot:2.0.0.M7
Elasticsearch:5.5, using Spring-Boot-Starter-Data-Elastic Search
Redis: spring-boot-starter-data-redis is used.

There is no mistake in using elasticsearch alone. pom will report an error as long as it introduces spring-boot-starter-data-redis.
