Hortonworks 教程构建失败 sun.security.provider.certpath.SunCertPathBuilderException

Question

我正在尝试从 "REALTIME EVENT PROCESSING IN HADOOP WITH NIFI, KAFKA AND STORM" Hortonworks 教程构建 "stream simulator"，特别是从它的 "LAB 0: INGEST, ROUTE AND LAND REAL TIME EVENTS WITH APACHE NIFI"。

http://hortonworks.com/hadoop-tutorial/realtime-event-processing-nifi-kafka-storm/#stream-simulator-lab0

为了让您大致了解这是什么，这里是 Hortoworks 页面的描述：“流模拟器是一个生成卡车事件数据的轻量级框架。模拟器使用纽约市卡车路线 (kml)，它定义了 driver 带有纬度和经度信息的道路路径。该模拟器使用 Akka 来简化并发、消息传递和继承。它有两个 Plain Old Java Objects (POJOS)，一个用于卡车，另一个用于生成事件的司机。”

当我尝试按照最新 Hortonworks Sandbox (HDP 2.4) 的指示在构建结束时构建模拟器时，Maven 报告此错误：

[ERROR] Failed to execute goal on project storm-kafka-0.8-plus: 
Could not resolve dependencies for project net.wurstmeister.storm:

sun.security.validator.ValidatorException: PKIX path building failed:

更详细的 (maven -e) 显示这些错误详细信息：

这里是 pom.xml 导致构建错误：

有什么解决办法吗？请帮忙！

更新：下一次构建错误

修复证书问题后，出现下一个错误：

您的 Maven 插件正在尝试连接到 https 远程存储库，即 https://clojars.org/repo/

您可以使用此 post 中的解决方案之一：

Problems using Maven and SSL behind proxy

我推荐的解决方案是：

（步骤可能因浏览器而异）

使用浏览器（使用chrome）前往https://clojars.org/repo/
单击锁定图标并选择 "Details" 然后单击 "View certificate"
转到 "Details" 选项卡并选择 "Copy to File"
选择类型 "Base 64 X.509 (.CER)" 并将其保存在某处
现在打开命令提示符并键入（使用您自己的路径）：

keytool -import -file C:\temp\mavenCert.cer -keystore C:\temp\mavenKeystore
现在您可以运行使用参数
再次执行命令
-Djavax.net.ssl.trustStore=C:\temp\mavenKeystore
linux下使用绝对路径

-Djavax.net.ssl.trustStore=/tmp/mavenKeystore

现在你可以运行 maven构建为：

/root/maven/bin/mvn clean package -Djavax.net.ssl.trustStore=C:\temp\mavenKeystore
