解决SBT下载依赖慢的问题

直接开干，两步结束战斗。

1·编写sbt repositories

vi ~/.sbt/repositories

2·添加以下内容

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

wq，保存退出，重新打开idea，打开你的scala项目即可。

解决maven下载依赖慢的问题

vi settings.xml

把以下内容复制进去

 <?xml version="1.0" encoding="UTF-8"?>
<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0 http://maven.apache.org/xsd/settings-1.0.0.xsd">
    <mirrors>
        <!-- 阿里云仓库 -->
        <mirror>
            <id>alimaven</id>
            <mirrorOf>central</mirrorOf>
            <name>aliyun maven</name>
            <url>http://maven.aliyun.com/nexus/content/repositories/central/</url>
        </mirror>


        <!-- 中央仓库1 -->
        <mirror>
            <id>repo1</id>
            <mirrorOf>central</mirrorOf>
            <name>Human Readable Name for this Mirror.</name>
            <url>http://repo1.maven.org/maven2/</url>
        </mirror>


        <!-- 中央仓库2 -->
        <mirror>
            <id>repo2</id>
            <mirrorOf>central</mirrorOf>
            <name>Human Readable Name for this Mirror.</name>
            <url>http://repo2.maven.org/maven2/</url>
        </mirror>
    </mirrors> 

</settings>

wq，保存，把刚刚建立的settings.xml文件复制maven设置目录，替换原本的settings.xml文件，当然了你也可以直接编辑原版的settings.xml文件，把以上内容添加进去
