今天閒來無事，自己搭了一個springboot+maven框架，可搭建後，pom檔案一直報錯報錯如下:

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

經過仔細排查  發現只需改成這樣就行：

需要注意的是：有時會提示

spring-boot-starter-test包不存在，然後編譯器也無法下載，這時可以去maven倉庫看看這個包對應的版本號，修改即可
