sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath
下载maven 依赖时报错sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath
解决方案:在Settings的Runner中将VM Options改为-Dmaven.wagon.http.ssl.insecure=true -Dmaven.wagon.http.ssl.allowall=true
之后就下载正常了
