肖壹刀: org.springframework:spring-aop:jar:4.3.11.RELEASE failed to transfer from https://repo.maven.apache.org/maven2 during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework:spring-aop:jar:4.3.11.RELEASE from/to central (https://repo.maven.apache.org/maven2): 不知道这样的主机。 (repo.maven.apache.org) Try to run Maven import with -U flag (force update snapshots) 这个报错是为什么啊
