我正在使用OSS NEXUS并尝试为常春藤设置代理回购。
有关于如何执行此操作的文章：http://www.scala-sbt.org/release/docs/Proxy-Repositories.html
我已经成功设置了maven central的代理，我看到nexus在浏览这些回购时已经缓存了文物。但常春藤代理不起作用。
我为这些网址创建了代理回购（maven）：
https://dl.bintray.com/sbt/sbt-plugin-releases/
http://repo.typesafe.com/typesafe/ivy-releases/
http://repo.scala-sbt.org/scalasbt/sbt-plugin-releases/
http://repo.typesafe.com/typesafe/releases/
为这四个代理回购创建了组回购（proxy-ivy）。
我已删除〜/ .sbt并运行sbt。在那里：
