我正在尝试在 sbt 中下载 Hive jar，但出现以下错误。有没有人遇到过这个？

请告诉我创建 GenericUDF 类所需的正确配置单元版本是什么

这是我的 SBT 文件

name := "Test"

version := "0.1"

scalaVersion := "2.11.8"


libraryDependencies += "org.apache.hive" % "hive-exec" % "1.2.1"

以下是我收到的错误消息

【解决方案1】：

请尝试使用以下 SBT，它应该会有所帮助。

name := "测试" 版本：=“0.1” scalaVersion := "2.11.8" libraryDependencies ++= Seq("org.apache.hive" % "hive-exec" % "1.2.1").map(_.exclude("org.pentaho", "pentaho- aggdesigner-算法"))
