Logback 依赖性阻止 SBT 离线运行

这是一个细化的上一个问题 https://stackoverflow.com/questions/23014492/sbt-0-13-1-offline更密切地归因于问题。

我正在尝试确认我可以离线运行我的 SBT 项目。我可以，除非 logback 是我的库依赖项之一。为什么 logback 会触发问题？我做了一个简单的例子，仅包含一个 build.sbt 和一个“hello world”应用程序......

构建.sbt用一堆随机依赖来证明这一点：

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"
)

My steps

1. Delete ~/.ivy2, ~/.sbt, and target/在我的项目中，只是为了确定
2. 确保连接到互联网，然后执行sbt run。我的hello world运行成功
3. 断开互联网连接
4. sbt clean
5. sbt run。构建失败，logback 作为未解决的依赖项
6. 删除 logback 依赖项并sbt run再次。你好世界运行。

这是步骤 5 中的错误：

Update:

使用lastSBT中的命令有一个lot用于依赖性解析的调试信息。下面是 Akka 成功解析的示例：

[info] Resolving com.typesafe.akka#akka-actor_2.10;2.3.1 ...

这是 Logback 的失败：

我可以确认缓存中的以下文件（不是“~/.ivy/local”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

当我尝试时，该文件确实是从 ~/.ivy2/cache 解析的。我没有 ~/.ivy2/local 因为我不在本地发布。您是否可能有一个 ivysettings.xml 文件（在 Linux 上，尝试locate ivysettings.xml）这扰乱了一些ivy缓存属性 https://ant.apache.org/ivy/history/latest-milestone/settings/caches.html，如解析缓存目录？为什么你只对那一个罐子有问题仍然是一个谜......

更新：这似乎是 SBT 0.13.1 中的回归；它在 0.13.0 中工作，正如 OP 自己发现的那样（参见他的答案），它在 0.13.2 中被修复。
