Question

我试图了解离线使用SBT 0.13.1。我的目标是将任何必要的东西带到USB记忆棒上的离线环境中。我认为如果复制了常春藤缓存，那么SBT可以从中提取所需的一切，但事实并非如此。

例如......

我首先要删除.ivy2文件夹，以确定。现在，在线时我使用以下build.sbt和project/plugins.sbt文件来创建我的eclipse项目。来自SBT 0.13.1

build.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")

在我离线的同一个计算器上，现在sbt clean eclipse给出了许多未解决的依赖错误。 E.g。

离线工作时真的无法清理吗？

我注意到SBT正在查看.ivy2/local，但是没有这样的文件夹。只有＆＃39; .ivy2 / cache＆＃39;。

更新

建议添加.ivy2 / local不起作用。它提供了许多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thr目录的格式为org.scala-lang

更新2

似乎问题是由与logback的一些交互引起的。我已经为我的问题here创建了一个更清晰的版本，我接受了答案，表明这应该是＆＃39;开箱即用。

Answer 1

我不确定这会有效，但我想您需要在Build.scala（或build.sbt）中添加另一个resolver，如下所示：

resolvers += "ivy2 cache" at "/home/user/.ivy2/cache"

如果有效，请告诉我，我也很好奇。

修改

我试了一下，然后sbt会查看你的ivy2缓存，进入你的build.sbt并添加以下内容：

resolvers += Resolver.file("ivy2 cache", file("/path/to/your/ivy2/cache/"))(Resolver.ivyStylePatterns)

现在SBT也应该查看该目录。

Answer 2

如果您在线构建项目，那么您可以在之后离线。基本上，您只是想将〜/ .ivy2文件夹（可能是〜/ .sbt文件夹 - 不确定）从之前完成构建和依赖性解析的位置复制到您的环境中。

删除项目中的目标/，然后离线，我可以看到这确实导致资源得到解决。
