SBT-修改资源库地址

做大数据开发, 用scala的都会用到sbt来打包依赖, 但是sbt默认配置里连接的国外地址, 根本就下不下来依赖包, 而且还有的地址是https的, 连接都被拒绝了, 所以我们就来修改sbt默认的配置.

首先, 我的系统是mac, 不管是用idea装的scala插件里带的sbt, 还是用Homebrew安装的sbt, 都会在用户目录下有个.sbt文件夹, 执行ll -a即可看到.

方法一

进入.sbt文件夹, 创建一个名叫repositories的文件, 默认应该是没有的, 并加入以下内容, 来覆盖默认配置

[repositories]
  local
  aliyun: http://maven.aliyun.com/nexus/content/groups/public/
  maven-central: http://repo1.maven.org/maven2/
  sbt-maven-releases: http://repo.scala-sbt.org/scalasbt/maven-releases/, bootOnly
  sbt-maven-snapshots: http://repo.scala-sbt.org/scalasbt/maven-snapshots/, bootOnly
  typesafe-ivy-releases: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
  sbt-ivy-snapshots: http://repo.scala-sbt.org/scalasbt/ivy-snapshots/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly

可见其中加入了阿里云的maven地址, 之前用过开源中国的, 后来他们干不下去了, 这次阿里云接盘, 应该不会轻易的狗带.

方法二

理论上添加以上配置后即可覆盖原来的默认配置, 然而我的sbt好像死活就是不行, 所以我还有第二个比较hacker的方法, 既然默认配置覆盖不掉, 那我就把默认配置改了.

我的sbt是用Homebrew安装的, 默认安装位置在 /usr/local/Cellar/sbt, 此处有一个bin文件夹和一个conf文件夹, 我们要破坏的jar包就是bin下的sbt-launch.jar文件.
tar解压sbt-launch.jar文件可以得到以下文件结构:

total 72
drwxr-xr-x   3 wdp  staff   102B  5 12  2016 META-INF

drwxr-xr-x  24 wdp  staff   816B  5 12  2016 xsbti

默认的配置文件就在sbt文件夹下的sbt.boot.properties文件, 对此文件内的内容进行替换, 如下:

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

[app]
  org: ${sbt.organization-org.scala-sbt}
  name: sbt
  version: ${sbt.version-read(sbt.version)[1.0.0-M4]}
  class: ${sbt.main.class-sbt.xMain}
  components: xsbti,extra
  cross-versioned: ${sbt.cross.versioned-false}
  resources: ${sbt.extraClasspath-}

[repositories]
  local
  aliyun: http://maven.aliyun.com/nexus/content/groups/public
  maven-central: http://repo1.maven.org/maven2/
  sbt-maven-releases: http://repo.scala-sbt.org/scalasbt/maven-releases/, bootOnly
  sbt-maven-snapshots: http://repo.scala-sbt.org/scalasbt/maven-snapshots/, bootOnly
  typesafe-ivy-releases: http://repo.typesafe.com/typesafe/ivy-releases/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly
  sbt-ivy-snapshots: http://repo.scala-sbt.org/scalasbt/ivy-snapshots/, [organization]/[module]/[revision]/[type]s/[artifact](-[classifier]).[ext], bootOnly

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

[ivy]
  ivy-home: ${sbt.ivy.home-${user.home}/.ivy2/}
  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}

修改完成, 再执行jar -cfM ./sbt-launch.jar .打成jar包, 把bin目录下的原始jar包替换掉即可, 这次保证妥妥的.

附上我改好的jar包下载地址, 送给懒得自己动手的人们, 传送门 -> sbt-launch.jar
