Scala：对象配置文件不是包 com.amazonaws.auth 的成员

Question

我遇到了构建问题。这是我的 sbt 文件：

name := "SparkPi"
version := "0.2.15"
scalaVersion := "2.11.8"

// https://mvnrepository.com/artifact/org.apache.spark/spark-core_2.10
libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "2.0.1"

// old:
//libraryDependencies += "org.apache.spark" %% "spark-core" % "2.0.1"

// https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk
libraryDependencies += "com.amazonaws" % "aws-java-sdk" % "1.0.002"

scalacOptions ++= Seq("-feature")

这是我看到的完整错误消息：

[info] Set current project to SparkPi (in build file:/Users/xxx/prog/yyy/)
    [info] Updating {file:/Users/xxx/prog/yyy/}yyy...
    [info] Resolving jline#jline;2.12.1 ...
    [info] Done updating.

    [error] /Users/xxx/prog/yyy/src/main/scala/PiSpark.scala:87: not found: type ProfileCredentialsProvider

    [error]                     ^
    [error] two errors found
    [error] (compile:compileIncremental) Compilation failed
    [error] Total time: 14 s, completed Nov 3, 2016 1:43:34 PM

这是我尝试使用的导入：

import com.amazonaws.services.s3._
import com.amazonaws.auth.profile._

如何在 Scala 中导入 com.amazonaws.auth.profile.ProfileCredentialsProvider？

编辑

修改了sbt文件，spark核心版本对应Scala版本，新内容：

name := "SparkPi"
version := "0.2.15"
scalaVersion := "2.11.8"

// https://mvnrepository.com/artifact/org.apache.spark/spark-core_2.11
libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.0.1"

// old:
//libraryDependencies += "org.apache.spark" %% "spark-core" % "2.0.1"

// https://mvnrepository.com/artifact/com.amazonaws/aws-java-sdk
libraryDependencies += "com.amazonaws" % "aws-java-sdk" % "1.0.002"

scalacOptions ++= Seq("-feature")

您正在使用 scalaVersion := "2.11.8"，但库依赖项有下划线 2.10 spark-core_2.10，这很糟糕。

libraryDependencies += "org.apache.spark" % "spark-core_2.10" % "2.0.1"
                                                          ^

将2.10 更改为2.11

libraryDependencies += "org.apache.spark" % "spark-core_2.11" % "2.0.1"
