尝试创建jar时无法解决依赖关系错误

Question

我正在尝试构建一个Scala jar文件以在spark中运行它.
我正在学习本教程.
试图为使用SBT建jar文件时,在这里,我面临着以下错误

Answer 1

您将依赖项定义为

"org.apache.spark" %% "spark-core" % "1.0.2"

这%%指示sbt将当前的scala版本替换为工件名称.显然,火花是为整个2.10 scala 家族建造的,没有针对2.10.1,2.10.2的特定罐子......

因此,您所要做的就是将其重新定义为:

"org.apache.spark" % "spark-core_2.10" % "1.0.2"
