scala - 由于 Unresolved 依赖关系，无法构建 sbt 0.12.0-RC1

Question

我正在尝试按照 https://github.com/harrah/xsbt 的说明构建 sbt 0.12.0-RC1信，但它无法下载先前版本的 sbt。

Getting org.scala-sbt sbt_2.9.1 0.12.0-M2 ...

在构建 sbt 0.12-RC1 之前，您需要安装 sbt 0.12-M2。

这是在“Build from source”点3下:

Note that sbt is always built with the previous stable release. For example, the 0.12 branch is built with 0.12.0-M2, the v0.11.2 tag is built with 0.11.1, and the v0.11.0 tag is built with 0.10.1.

我想只要从 their repository 下载，你会感觉更好。 .
