        import
       		
      	
     
    

报如下异常：

Project build error: Non-resolvable import POM: Failure to transfer org.springframework.cloud:spring-cloud-dependencies:pom:Dalston.RC1 from was cached in the local repository, resolution will not be reattempted until the update interval of spring-milestones has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.cloud:spring-cloud-dependencies:pom:Dalston.RC1 from/to spring-milestones (): Received fatal alert: protocol_version to

去maven仓库查了一下， ，并没有Dalston.RC1这个version，参照帖子建议，改成Dalston.SR4，完美解决。
