Scala的安装及环境配置



一、本地安装

1.安装Scala到C盘上

( 提取码:346r )


2.配置本地环境变量


3.检测是否安装完成


二、IDEA安装Scala

(1)新建一个maven项目

(2)修改依赖配置 pom.xml

(3)将java文件名改为scala

(4)下载Scala插件

(5)重启idea (6)编写一个Scala程序

object HelloWorld {
  def main(args: Array[String]): Unit = {
    println("HelloWorld")
  }
}

(7)运行结果


三、在本地后台运行Scala的jar包

(1)获取程序路径 (2)修改依赖中的路径 (3)打包 (4)获取路径在后台中运行 (5)使用Scala命令运行
