scala开发环境配置(windows环境)

确认系统已经安装java8或以上的jdk

下载scala-2.11.8.msi

https://www.scala-lang.org/download/all.html

下载sbt-1.2.8.msi

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

分别安装scala和sbt

配置sbt

1. 修改sbt/conf/sbtconfig.txt

-Xmx512M
-XX:MaxPermSize=256m
-XX:ReservedCodeCacheSize=128m
-Dsbt.log.format=true
# 如果需要修改源
-Dsbt.override.build.repos=true
# 如果希望修改本地仓地址
-Dsbt.boot.directory=D:/sbt/.sbt/boot
-Dsbt.ivy.home=D:/sbt/.ivy2
-Dsbt.global.base=D:/sbt/.sbt
-Dsbt.repository.config=D:/sbt/repositories
# 如果需要设置代理
-Dsbt.repository.secure=false
-Dhttp.proxyHost=proxyhost
-Dhttp.proxyPort=proxyport
-Dhttp.proxyUser=user
-Dhttp.proxyPassword=password
-Dhttps.proxyHost=proxyhost
-Dhttps.proxyPort=proxyport
-Dhttps.proxyUser=user
-Dhttps.proxyPassword=password

2.修改源，如果sbt.repository.config不设置,需要在用户目录下的.sbt中新建repositories文件,设置了则在设置的目录中创建

如果使用华为云的sbt镜像则内容修改为

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

下载并安装idea,下载scala-intellij-bin-2019.2.15.zip插件,解压到idea插件目录

打开idea,新建scala-sbt项目

1. 设置sbt为系统安装的版本而不是idea内置的

   

   vm参数的设置和sbtconfig.txt一样, 启动器为安装的sbt启动器文件路径

2. 为项目添加scala-sdk

   

   添加成功后会出现在modules中

   

3. 设置scala目录为源目录( 注意不设置会导致找不到主类入口)

   

4. 在scala目录下新建com目录，并添加HelloWord.scala文件,内容为

   package com
   
   object HelloWorld{
     def main (args: Array[] ): Unit = {
         print("Hello World!")
     }
   }

5. 右键运行HelloWorld文件
