Scala IntelliJ库导入错误

我是scala新手，正在尝试在build.sbt中导入以下库。IntelliJ执行自动更新时，我会出现以下错误：

Error while importing sbt project:

这是我的build.sbt文件：

name := "Stream-Processing"

version := "1.0"

scalaVersion := "2.11.8"

libraryDependencies += "org.apache.spark" %% "spark-sql" % "2.4.4"

// https://mvnrepository.com/artifact/org.apache.spark/spark-sql-kafka-0-10_2.12
libraryDependencies += "org.apache.spark" %% "spark-sql-kafka-0-10" % "2.4.4"

// https://mvnrepository.com/artifact/org.apache.kafka/kafka-clients
libraryDependencies += "org.apache.kafka" %% "kafka-clients" % "2.3.1"

// https://mvnrepository.com/artifact/mysql/mysql-connector-java
libraryDependencies += "mysql" % "mysql-connector-java" % "8.0.18"

// https://mvnrepository.com/artifact/org.mongodb.spark/mongo-spark-connector
libraryDependencies += "org.mongodb.spark" %% "mongo-spark-connector" % "2.4.1"

我做了一个Scala项目只是为了确保Spark工作，我的python项目也使用Kafka工作，所以我确信这不是Spark/Kafka的问题。有什么原因导致我出现这个错误吗？

尝试在

卡夫卡客户端之前删除一个
%
：

libraryDependencies+=“org.apache.kafka”%“kafka客户端”%“2.3.1”

SBT中
%%
的语义是，它将使用的Scala版本附加到工件名称中，因此它变成
org.apache.kafka:kafka-clients_2.11:2.3.1
，正如错误消息所示。请注意
\u 2.11
后缀。

这是Scala库的一个很好的简写，但当与Java libs一起使用时，初学者可能会感到困惑。

Kafka客户端是一个Java库，而不是Scala库。因此，您只需要使用一个
%%
而不是两个
%%
：
libraryDependencies+=“org.apache.kafka”%%“kafka客户端”%%“2.3.1”
这里的链接非常明确。kafka客户端是Java库，而不是Scala库。因此，您只需要使用一个
%%
而不是两个
%%
：
libraryDependencies+=“org.apache.kafka”%%“kafka客户端”%%“2.3.1”
您在那里的链接对此非常明确。
