下载sbt-1.1.6.tgz

.bashrc

export PATH=~/bigdata/sbt:$PATH
alias sbt=~/bigdata/sbt/bin/sbt

---------------------------------------------------------------------------------------------------------------------------------------------------

~/bigdata/sbt/start.sh

#!/bin/bash
SBT_OPTS="-Xms512M -Xmx1536M -Xss1M -XX:+CMSClassUnloadingEnabled -XX:MaxPermSize=256M"
java $SBT_OPTS -jar ~/bigdata/sbt/bin/sbt-launch.jar "$@"

~/bigdata/sbt/conf/sbtconfig.txt

# Set the java args to high

-Xmx512M

-XX:MaxPermSize=256m

-XX:ReservedCodeCacheSize=128m



# Set the extra SBT options

-Dsbt.log.format=true

-Dsbt.boot.directory=~/bigdata/sbt/.sbt/boot
-Dsbt.global.base=~/bigdata/sbt/.sbt
-Dsbt.ivy.home=~/bigdata/sbt/.ivy2
-Dsbt.repository.config=~/bigdata/sbt/conf/repo.properties
-Dsbt.repository.secure=false

感觉上面的那个启动脚本也不是很必要,

按照上面这样配置完以后,重新打开终端,输入sbt就可以启动了

---------------------------------------------------------------------------------------------------------------------------------------------------

建立一個文件叫test.

object HelloWorld{
  def main(args: Array[String]) {
    println("Hello, SBT")
  }

}

---------------------------------------------------------------------------------------------------------------------------------------------------

在當前路徑下啓動sbt
