Question

这是previous question的改进，更接近问题。

我试图确认我可以离线运行我的SBT项目。我可以，除非logback是我的libraryDependencies之一。为什么logback会触发问题？我做了一个简单的例子，它只包含一个build.sbt和一个'hello world＆＃39;应用...

build.sbt 与一堆随机依赖关系来证明这一点：

name := "testProject"

version := "0.0.1"

scalaVersion := "2.10.3"

libraryDependencies ++= Seq(
    "org.apache.commons" % "commons-math3" % "3.2",
    "com.amazonaws" % "aws-java-sdk" % "1.4.0.1",
    "ch.qos.logback" % "logback-classic" % "1.1.1",
    "com.typesafe.akka" %% "akka-actor" % "2.3.1", 
    "com.typesafe.akka" %% "akka-remote" % "2.3.1",
    "org.scalaz" %% "scalaz-core" % "7.0.3"
)

我的步骤

删除项目中的~/.ivy2，~/.sbt和target/，以确保
确保已连接到互联网，并执行sbt run。我的hello world成功运行
断开互联网连接
sbt clean
sbt run。构建失败，并将logback作为未解析的依赖项
再次删除logback依赖关系和sbt run。 Hello world运行。

这是第5步中的错误：

更新

在SBT中使用last命令，有一个用于依赖项解析的 lot 调试信息。以下是Akka成功解决的一个例子：

[info] Resolving com.typesafe.akka#akka-actor_2.10;2.3.1 ...
[debug] sbt-chain: Checking cache for: dependency: com.typesafe.akka#akka-actor_2.10;2.3.1 {compile=[default(compile)]}

[debug] == resolving dependencies com.typesafe.akka#akka-actor_2.10;2.3.1->com.typesafe#config;1.2.0 [compile->master(*)]

这是Logback的失败：

我可以在缓存中确认以下文件（而不是＆＃39;〜/ .ivy / local＆＃39;文件夹）：

~/.ivy2/cache/ch.qos.logback/logback-classic$ ls
ivy-1.1.1.xml  ivy-1.1.1.xml.original  ivydata-1.1.1.properties  jars

Answer 1

它无法在您当地的常春藤缓存中找到它，修复该问题并解决了您的问题。

尝试清除你的常春藤缓存，也许它已经腐败了。

Answer 2

当我尝试它时，文件确实从〜/ .ivy2 / cache解析。我没有〜/ .ivy2 / local因为我不在本地发布。您是否有可能有一个ivysettings.xml文件（在Linux上，尝试locate ivysettings.xml）与一些Ivy cache attribute混淆，如resolutionCacheDir？为什么你只对那个罐子有问题仍然是一个谜......

更新：这似乎是SBT 0.13.1的回归;它的工作频率为0.13.0，正如OP自己发现的那样（见他的答案），它在0.13.2中得到了修正。

Answer 3

SBT 0.13.2在这个问题发布3天后发布，似乎解决了这个问题。我不知道这是否是一个已知问题，但为SBT 0.13.2列出的更改包括

解决问题，常春藤+。依赖范围不正确翻译成maven。
