新的火花世界和尝试用我在网上找到的scala编写的数据集示例

在通过SBT运行时,我继续收到以下错误

org.apache.spark.sql.AnalysisException: Unable to generate an encoder for inner class

知道我在俯瞰什么

也可以随意指出编写相同数据集示例的更好方法

谢谢

我是java/gradle安装的新手,并且能够使用此处提供的示例构建jar文件.同时也实现了Jacoco代码覆盖工具.
但遇到以下问题

• 无法构建RPM,Tried ospackage-plugin但它只是不生成任何东西(在插件的github页面上提供的示例)
• Jacoco没有生成突出显示的源代码html文件？它的产生,直到像法击穿这个,但不能产生单独的源代码文件

我的build.gradle文件如下

plugins {
  id "nebula.ospackage" version "3.2.0"
} 

apply plugin: 'nebula.ospackage'
apply plugin: 'java'
apply plugin: "jacoco"

   mavenCentral()
   jcenter()

dependencies {
  testCompile 'org.testng:testng:6.8'
  compile 'log4j:log4j:1.2.17'
