你需要输入你的网络根证书到你的jre cacerts使用keytool。有关非常详细的步骤，请参阅[this]（http://stackoverflow.com/a/40757655/1802348） – positivecrux

无法工件com.mapr转移：MAPR根：POM：从/ 2.0-快照scala-tools.org（http://scala-tools.org/repo-releases）： sun.security.validator.ValidatorException：PKIX路径构建失败： sun.security.provider.certpath.SunCertPathBuilderException：无法找到有效证明路径请求的目标 - > [求助1]

似乎要与SSL证书有问题。也许这篇文章是有帮助的：Problems using Maven and SSL behind proxy
