一、报错

Could not transfer artifact org.apache.maven.plugins:maven-install-plugin:pom:2.4 from/to alimaven (https://maven.aliyun.com/repository/central): sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

 

二、解决

添加参数

-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true
