SBT在Windows上的配置

1. 下载和安装SBT

下载SBT的windows版本，可以下载msi和zip两种格式，SBT下载

将下载好的sbt-1.3.5.zip解压到安装目录，并且配置环境变量即可

打开sbt的解压目录，可以看到如下的目录结构

2. 配置SBT

在conf目录下，有一个sbtconfig.txt，添加以下内容

里面的路径指向的就是你自己的sbt仓库的方法路径

-Dsbt.log.format=true
-Dfile.encoding=UTF8
-Dsbt.global.base=e:/sbt/.sbt
-Dsbt.boot.directory=e:/sbt/.sbt/boot/
-Dsbt.repository.config=e:/sbt/.sbt/repo.properties
-Dsbt.ivy.home=e:/sbt/.ivy2
-Dsbt.override.build.repos=true
-Xmx512M
-Xss2M
-XX:+CMSClassUnloadingEnabled

将conf目录下的repo.properties复制到上面的指定目录，我复制到E:/sbt/.sbt/目录下即可

修改repo.properties的内容为国内的镜像源，实测阿里云的不要好使，可以更换成华为的镜像源

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

方法一：配置完成之后，打开cmd执行sbt，等待下载完成即可

方法二：使用IDEA配置SBT，新建SBT项目，可以参照使用IDEA和SBT构建Spark程序这篇文章，之后打开IDEA设置

设置SBT的VM parameters，设置值和上面sbt目录下的sbtconfig.txt内容一致

-Dsbt.log.format=true
-Dfile.encoding=UTF8
-Dsbt.global.base=e:/sbt/.sbt
-Dsbt.boot.directory=e:/sbt/.sbt/boot/
-Dsbt.repository.config=e:/sbt/.sbt/repo.properties
-Dsbt.ivy.home=e:/sbt/.ivy2
-Dsbt.override.build.repos=true
-Xmx512M
-Xss2M
-XX:+CMSClassUnloadingEnabled

设置SBT的Launcher为Custom，选择自己sbt安装目录下的bin目录下的sbt-launch.jar即可

3. 扩展修改

若非必要情况，个人不建议修改一下内容

可以将上面的sbt-launch.jar中的/sbt/sbt.boot.properties文件修改为以下内容

[scala]
  version: ${sbt.scala.version-auto}

[app]
  org: ${sbt.organization-org.scala-sbt}
  name: sbt
  version: ${sbt.version-read(sbt.version)[1.3.5]}
  class: ${sbt.main.class-sbt.xMain}
  components: xsbti,extra
  cross-versioned: ${sbt.cross.versioned-false}
  resources: ${sbt.extraClasspath-}
