使用sbt 0.13.5

wget http://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/sbt-launch/0.13.5/sbt-launch.jar

新建sbt脚本在/usr/local/sbt/ 下 并加入执行权限。

#!/bin/bash
SBT_OPTS="-Xms512M -Xmx1536M -Xss1M -XX:+CMSClassUnloadingEnabled "
java $SBT_OPTS -jar `dirname $0`/sbt-launch.jar "$@"

/usr/local/sbt/sbt sbt-version 

进行sbt初始化。会下载一些文件。

出现超时报错：

export JAVA_OPTS="$JAVA_OPTS -Dhttp.proxyHost=yourserver -Dhttp.proxyPort=8080 -Dhttp.proxyUser=username -Dhttp.proxyPassword=password"

然后重试，成功后

会打印出sbt版本 为0.13.5

新建sbt配置文件：

name := "Simple Project"

version := "1.0"

scalaVersion := "2.11.8"

val sparkVersion = "2.3.3"


resolvers ++= Seq(
  "apache-snapshots" at "http://repository.apache.org/snapshots/"
)

libraryDependencies ++= Seq(
  "org.apache.spark" %% "spark-core" % sparkVersion,
  "org.apache.spark" %% "spark-sql" % sparkVersion,
  "org.apache.spark" %% "spark-mllib" % sparkVersion,
  "org.apache.spark" %% "spark-streaming" % sparkVersion,
  "org.apache.spark" %% "spark-hive" % sparkVersion,
  "mysql" % "mysql-connector-java" % "5.1.6"
)

没有用到的就删掉。不然会很慢。
