如何配置帶有內部Nexus存儲庫的SBT？

Question

我無法通過當前網絡訪問像repo1.maven.org這樣的外部主機。儘管我有一個內部的Nexus存儲庫。如何設置SBT以使用該存儲庫？

實例錯誤，我得到：

C:\Users\myusername>sbt sbt-version 
Getting net.java.dev.jna jna 3.2.3 ...

我還沒有嘗試過這個自己，但在目前的SBT 0.12理應Global repository setting功能是爲那種情況產生：

定義庫使用通過在~/.sbt/repositories中放置獨立的[repositories]部分（請參閱Launcher Specification頁面）並將-Dsbt.override.build.repos=true傳遞給sbt。只有該文件中的存儲庫將被啓動器用於檢索sbt和Scala，並在檢索項目依賴關係時由sbt使用。
