問題：

建立maven專案的時候，新增parent標籤，報錯誤：

Project build error: Non-resolvable parent POM for model:maven01:0.0.1-SNAPSHOT: Failure to transfer org.springframework.boot:spring-boot-starter-parent:pom:1.5.3.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:1.5.3.RELEASE from/to central (https://repo.maven.apache.org/maven2): connect timed out and 'parent.relativePath' points at wrong local POM

解決：

maven使用國內代理————阿里映象
