如何使用内部 Nexus 存储库配置 SBT？

Question

我无法通过我当前的网络访问像 repo1.maven.org 这样的外部主机。不过，我有一个内部 Nexus 存储库。如何设置 SBT 以使用该存储库？

我得到的错误示例：

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

我自己没有尝试过，但据说当前 sbt 0.12 中的 Global repository setting 功能是针对这种情况创建的：

通过在~/.sbt/repositories 中放置一个独立的[repositories] 部分（参见Launcher Specification 页面）来定义要使用的存储库，并将-Dsbt.override.build.repos=true 传递给sbt。只有该文件中的存储库将被启动器用于检索 sbt 和 Scala，以及在检索项目依赖项时被 sbt 使用。
