Scala SBT 0.13.1离线

我试图理解SBT 0.13.1的离线使用。我的目标是用U盘将任何必要的东西带到离线环境中。我认为，如果常春藤缓存被复制，那么SBT可以从中提取它所需要的一切，但事实似乎并非如此

例如

我将从删除.ivy2文件夹开始，只是为了确定。现在，在联机时，我使用以下

build.sbt

和

project/plugins.sbt

文件来创建我的eclipse项目。从SBT 0.13.1开始

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"
)

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

项目/插件。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"
)

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

我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性错误。例如

脱机工作时真的不可能清洁吗

我注意到SBT正在查看

.ivy2/local

，但没有这样的文件夹。仅“.ivy2/cache”

更新：

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"
)

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

建议添加。ivy2/local无效。它给人许多畸形的感觉

[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

它正在寻找一个目录org/scala-lang等，但缓存中的目录是org.scala-lang的形式

这个问题似乎是由于与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，并且我接受了这个“应该”开箱即用的答案。

我不确定这是否可行，但我想您需要在

Build.scala

（或

Build.sbt

）中添加另一个版本，如下所示：

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

让我知道这是否有效，我也很好奇

编辑：

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"
)

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

我试过了，sbt确实在你的

ivy2

缓存中查找，进入你的

build.sbt

并添加这一行：

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

---

现在

SBT

也应该在该目录中查找。

如果您在线构建项目，那么之后就可以脱机。 基本上，您只需要将~/.ivy2文件夹（可能还有~/.sbt文件夹-不确定）从以前执行过构建和依赖项解析的位置复制到您的环境中

在项目中删除target/然后脱机，我可以看到这确实会导致资源被解析

[info] Resolving org.fusesource.jansi#jansi;1.4 ...
[info] Done updating.
[info] Compiling 4 Scala sources to [...]

---

似乎对我不起作用。脱机时是否以任何方式更改配置？否。我刚刚关闭wifi并重新运行一个基于sbt 0.13.1的项目（我经常使用brew switch sbt x.x.x）。这里没有任何问题-您以前成功地构建了它？除了这两个文件夹之外，可能还有另一个我不知道需要的组件，但它似乎可以毫无问题地从ivy缓存解决依赖关系。似乎已经修复了scala lang依赖关系。现在它的后备箱坏了。它使用了错误的命名约定logback classic/1.1.1/ivys/ivy.xml，而不是logback classic/ivy-1.1.1.xml。我想这与

（Resolver.ivyStylePatterns）

有关，它将

ivys

部分附加到路径中，不幸的是，这只是一个猜测。是否尝试

设置为脱机：=true

？我也试过了，但没有改变。我对offline:=true的理解是，它可以阻止快照不断地检查，但无论如何，我都不会直接使用任何快照。
