sbt-cassandra-connector 2.0.2的sbt未解决依赖性 [英] sbt unresolved dependency for spark-cassandra-connector 2.0.2

问题描述

build.sbt:

build.sbt:

val sparkVersion = "2.1.1";

libraryDependencies += "org.apache.spark" %% "spark-core" % sparkVersion % "provided";
libraryDependencies += "org.apache.spark" %% "spark-sql" % sparkVersion % "provided";
libraryDependencies += "org.apache.spark" %% "spark-streaming" % sparkVersion % "provided";

libraryDependencies += "com.datastax.spark" % "spark-cassandra-connector" % "2.0.2";
libraryDependencies += "org.apache.spark" % "spark-streaming-kafka-0-10_2.11" % sparkVersion;

输出:

[error] (myproject/*:update) sbt.ResolveException: unresolved dependency: com.datastax.spark#spark-cassandra-connector;2.0.2: not found

有什么主意吗?我是sbt和spark的新手.谢谢

Any idea? I am new to sbt and spark. Thanks

推荐答案

这是由于"com.datastax.spark" % "spark-cassandra-connector" % "2.0.2";没有 scala版本引起的，请参见 Maven回购:

This is caused by "com.datastax.spark" % "spark-cassandra-connector" % "2.0.2"; without scala version, see maven repo:

http://search.maven.org/#artifactdetails%7Ccom.datastax.spark%7Cspark-cassandra-connector_2.11%7C2.0.2%7Cjar

有2种解决方案:

1. "com.datastax.spark" % "spark-cassandra-connector_2.11" % "2.0.2"明确设置 Scala版本以获得依赖性
2. "com.datastax.spark" %% "spark-cassandra-connector" % "2.0.2"，将%%与工件ID 一起使用，这样， SBT 将自动基于您项目的 scala版本扩展到解决方案1 ​​.

1. "com.datastax.spark" % "spark-cassandra-connector_2.11" % "2.0.2" explicitly set Scala version for dependency
2. "com.datastax.spark" %% "spark-cassandra-connector" % "2.0.2", use %% with artifact id, this way, the SBT will auto base on your project's scala version to expand to the solution 1.
