In maven -> the following error when reimport

Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:1.3.8.RELEASE from/to alimaven (http://maven.aliyun.com/nexus/content/repositories/central/): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Online methods do not fly, and finally use this solution:

In https://maven.aliyun.com/mvn/search use GAV search

group : spring-boot-starter-parent
artifactId: spring-boot-starter-parent
version: 1.3.8.RELEASE
把.pom文件下载到maven仓库的org/springframework/boot/spring-boot/1.3.8.RELEASE/中

Then reimport it again
