SBT 0.13.1 离线

我试图了解 SBT 0.13.1 离线使用。我的目标是将离线环境所需的一切都存储在 U 盘上。我认为如果复制了 ivy 缓存，那么 SBT 就可以从中提取所需的所有内容，但情况似乎并非如此。

例如...

为了确定起见，我将首先删除 .ivy2 文件夹。现在，在线时我使用以下命令build.sbt and project/plugins.sbt文件来创建我的 Eclipse 项目。从 SBT 0.13.1 开始

构建.sbt：

name := "TestProject"

version := "0.0.1"

scalaVersion := "2.10.3"

libraryDependencies ++= Seq(
    "org.apache.commons" % "commons-math3" % "3.2",
    "ch.qos.logback" % "logback-classic" % "1.1.1"
)

项目/plugins.sbt：

addSbtPlugin("com.typesafe.sbteclipse" % "sbteclipse-plugin" % "2.4.0")

我仍然在同一台计算机上离线，现在sbt clean eclipse给出了许多未解决的依赖错误。例如。

离线工作真的无法清洁吗？

我注意到 SBT 正在寻找.ivy2/local，但没有这样的文件夹。只有“.ivy2/cache”。

Update:

添加 .ivy2/local 的建议不起作用。它给出了许多 MalformedURLException

[warn]  :: org.scala-lang#scala-library;2.10.3: ivy2 cache: unable to get resource for org/scala-lang#scala-library;2.10.3: res=/home/user/.ivy2/cache/org/scala-lang/scala-library/2.10.3/scala-library-2.10.3.pom: java.net.MalformedURLException: no protocol: /home/user/.ivy2/cache/org/scala-lang/scala-library/2.10.3/scala-library-2.10.3.pom

它正在寻找目录 org/scala-lang 等，但缓存中的目录格式为 org.scala-lang

Update 2

看来问题是由与 logback 的一些交互引起的。我已经为我的问题创建了一个更清晰的版本here https://stackoverflow.com/questions/23020066/logback-dependency-preventing-sbt-running-offline，并接受表明这“应该”开箱即用的答案。

如果您在线构建项目，那么之后就可以离线。 基本上，您只想将 ~/.ivy2 文件夹（可能还有 ~/.sbt 文件夹 - 不确定）从之前已完成构建和依赖项解析的位置复制到您的环境中。

删除项目中的 target/，然后离线，我可以看到这确实会导致资源得到解析。
