阿里云maven镜像无法使用，pom文件报错
Could not transfer artifact org.springframework.boot:spring-boot-starter-parent:pom:2.1.8.RELEASE from/to aliyunmaven (https://maven.aliyun.com/repository/public): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target
换成其他镜像没有这个问题
