sun.security.validator.ValidatorException,sun.security.provider.certpath.SunCertPathBuilderException

一.问题描述:最近搞大数据spark时,在idea中使用Maven出现如下异常,导致依赖的包无法下载sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target。二.解决方案:1.忽略SSL证书检查在install命令后加入参数“-Dmaven.wagon.http.ssl.insecuretrue -Dmaven.wagon.http.ssl.allowalltrue”执行2.然后在pom.xml上右键,选择reimport重新更新依赖即可。
