今天闲来无事，自己搭了一个springboot+maven框架，可搭建后，pom文件一直报错报错如下:
Project build error: Non-resolvable parent POM for com.example:demo:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:1.5.8.RELEASE from https://repo.maven.apache.org/maven2 was cached in the local repository, resolution
will not be reattempted until the update interval of central has elapsed or updates are forced. Original error: Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.5.8.RELEASE from/to central (https://repo.maven.apache.org/maven2):
connect timed out and 'parent.relativePath' points at wrong local POM
经过仔细排查 发现只需改成这样就行：
需要注意的是：有时会提示
spring-boot-starter-test包不存在，然后编译器也无法下载，这时可以去maven仓库看看这个包对应的版本号，修改即可
