centos7-- sbt的安装使用

sbt是一款类似于maven的构建工具

安装sbt

curl https://bintray.com/sbt/rpm/rpm > bintray-sbt-rpm.repo
mv bintray-sbt-rpm.repo /etc/yum.repos.d/
yum install sbt -y

配置其使用国内阿里云仓库源
在 .sbt下新建repositories文件

vim /root/.sbt/repositories
[repositories]
local
aliyun: http://maven.aliyun.com/nexus/content/groups/public
jcenter: http://jcenter.bintray.com
typesafe: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly

简单使用

构建hello项目

mkdir -p /root/project_sbt/hello
vim /root/project_sbt/hello/hw.scala    #项目代码
object Hi {
  def main(args: Array[String]) = println("Hi!")
}
vim /root/project_sbt/hello/build.sbt  #构建定义，类似于maven的pom.xml
lazy val root = (project in file("."))
  .settings(
    name := "hello",
    version := "1.0",
    scalaVersion := "2.12.2"
  )

开始打包

cd /root/project_sbt/hello
sbt clean package  也可以sbt回车，出现一个交互界面，再clean package
ls /root/project_sbt/hello/target/scala-2.12
