maven 构建项目时报错

Non-resolvable parent POM for com.itheima:integation-mybatis:0.0.1-SNAPSHOT: org.springframework.boot:spring-boot-starter-parent:pom:2.5.3 failed to transfer from http://maven.aliyun.com/nexus/content/groups/public/ during a previous attempt. This failure was cached in the local repository and resolution is not reattempted until the update interval of alimaven has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.5.3 from/to alimaven (http://maven.aliyun.com/nexus/content/groups/public/): transfer failed for http://maven.aliyun.com/nexus/content/groups/public/org/springframework/boot/spring-boot-starter-parent/2.5.3/spring-boot-starter-parent-2.5.3.pom and ‘parent.relativePath’ points at no local POM

解决方法：在仓库目录，把对应依赖的版本文件夹删除了，项目重新reload一下
