国内：如何解决Maven和SBT下载Jar包太慢

 

Maven 远程仓库

    <mirror>  
      <id>ui</id>  
      <mirrorOf>central</mirrorOf>  
      <name>Human Readable Name for this Mirror.</name>  
      <url>http://uk.maven.org/maven2/</url>  
    </mirror>  
    <mirror>  
      <id>ibiblio</id>  
      <mirrorOf>central</mirrorOf>  
      <name>Human Readable Name for this Mirror.</name>  
      <url>http://mirrors.ibiblio.org/pub/mirrors/maven2/</url>  
    </mirror>  
    <mirror>  
      <id>jboss-public-repository-group</id>  
      <mirrorOf>central</mirrorOf>  
      <name>JBoss Public Repository Group</name>  
      <url>http://repository.jboss.org/nexus/content/groups/public/</url>  
    </mirror>
    <mirror>
      <id>CN</id>
      <name>OSChina Central</name>                                    
      <url>http://maven.oschina.net/content/groups/public/</url>
      <mirrorOf>central</mirrorOf>
    </mirror>
    <mirror>  
      <id>repo2</id>  
      <mirrorOf>central</mirrorOf>  
      <name>Human Readable Name for this Mirror.</name>  
      <url>http://repo2.maven.org/maven2/</url>  
    </mirror>

说明：

1. 上面的地址前面三个只适合maven，sbt的ivy不适合，sbt需要的jar包在里面会找不到，从下面的配置可以看出。
2. oschina的镜像虽然都适用，但是访问速度真是慢
3. 最全面的仓库在校园网完全没办法访问

SBT

修改SBT的远程仓库地址有很多办法，这里采用直接修改sbt-lauch.jar/sbt/sbt.boot.properties的方式

[scala]
  version: ${sbt.scala.version-auto}

[app]
  org: ${sbt.organization-org.scala-sbt}
  name: sbt
  version: ${sbt.version-read(sbt.version)[0.13.9]}
  class: ${sbt.main.class-sbt.xMain}
  components: xsbti,extra
  cross-versioned: ${sbt.cross.versioned-false}
  resources: ${sbt.extraClasspath-}

[repositories]
  local
    Local-Maven-Repository: file:///D:/Java/java-repositories, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext]
    ibiblio-maven:http://maven.ibiblio.org/maven2/
    typesafe-ivy:https://dl.bintray.com/typesafe/ivy-releases/, [organization]/[module]/(scala_[scalaVersion]/)(sbt_[sbtVersion]/)[revision]/[type]s/[artifact](-[classifier]).[ext] 
  maven-central
    uk-repository: http://uk.maven.org/maven2/
    jboss-repository: http://repository.jboss.org/nexus/content/groups/public/

[boot]
  directory: ${sbt.boot.directory-${sbt.global.base-${user.home}/.sbt}/boot/}

[ivy]
  ivy-home: D:/Java/java-repositories
  checksums: ${sbt.checksums-sha1,md5}
  override-build-repos: ${sbt.override.build.repos-false}
  repository-config: ${sbt.repository.config-${sbt.global.base-${user.home}/.sbt}/repositories}

说明：

1. repositories 修改远程仓库地址
2. typesafe-ivy：目的是兼容ivy地址
3. ivy-home：指的是本地仓库地址，就是jar存在哪里
