sbt安装和配置镜像

安装

访问https://www.scala-sbt.org/download.html

下载安装包sbt-1.3.10.zip，如果网络原因下载慢可以从 https://ww.lanzous.com/icrmh8b 下载

wget https://piccolo.link/sbt-1.3.10.zip

解压

unzip sbt-1.3.10.zip

之后会有一个sbt文件夹

配置镜像

在用户主目录下创建.sbt文件夹，在新建repositories文件

cd 
mkdir .sbt
vim .sbt/repositories

repositories文件内容如下

[repositories]
local
huaweicloud-maven: https://repo.huaweicloud.com/repository/maven/
maven-central: https://repo1.maven.org/maven2/
sbt-plugin-repo: https://repo.scala-sbt.org/scalasbt/sbt-plugin-releases, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext]

编辑sbt目录下的conf目录中的sbtconfig.txt，添加如下内容-Dsbt.override.build.repos=true

vim conf/sbtconfig.txt

-Dsbt.override.build.repos=true

运行

切换到sbt下执行

./bin/sbt sbtVersion 

如果执行长时间无反应，可以尝试把https://ww.lanzous.com/icrptmf 的.ivy2.tar 解压覆盖到用户主目录

打包

新建一个项目，新建simple.sbt

name := "Simple Project"
version := "1.0"
scalaVersion := "2.11.8"
libraryDependencies += "org.apache.spark" %% "spark-core" % "2.1.0"

新建src/main/scala/SimpleApp.scala

/* SimpleApp.scala */
import org.apache.spark.SparkContext
import org.apache.spark.SparkContext._
import org.apache.spark.SparkConf
 
object SimpleApp {
def main(args: Array[String]) {
            val logFile = "file:///usr/local/spark/README.md" // Should be some file on your system
            val conf = new SparkConf().setAppName("Simple Application")
            val sc = new SparkContext(conf)
            val logData = sc.textFile(logFile, 2).cache()
            val numAs = logData.filter(line => line.contains("a")).count()
            val numBs = logData.filter(line => line.contains("b")).count()
            println("Lines with a: %s, Lines with b: %s".format(numAs, numBs))
    }
}

打包

../bin/sbt package

编译成功后在jar包在target/scala-2.11目录下
