Logback依赖性阻止SBT脱机运行 [英] Logback dependency preventing SBT running offline

问题描述

这是对上一个问题的改进，并且对该问题的归属也更紧密.

我试图确认我可以离线运行SBT项目.我可以，除非logback是我的libraryDependencies之一.为什么logback会引发问题?我已经做了一个简单的示例，其中仅包含一个build.sbt和一个"hello world"应用程序...

build.sbt ，带有一堆随机相关性以证明这一点:

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

1. 请确保在我的项目中删除~/.ivy2，~/.sbt和target/
2. 确保已连接到Internet，然后执行sbt run.我的问候世界成功运行
3. 断开与互联网的连接
4. sbt clean
5. sbt run.构建失败，并以未解决的依赖关系重新登录
6. 删除logback依赖性，然后再次sbt run.你好，世界奔跑.

这是步骤5中的错误:

更新:

在SBT中使用last命令，有 lot 条调试信息用于依赖性解析.这是Akka成功解析的示例:

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

解决方案

当我尝试使用该文件时，确实从〜/.ivy2/cache解析了该文件.我没有〜/.ivy2/local，因为我没有在本地发布.是否可能有一个ivysettings.xml文件(在Linux上，请尝试locate ivysettings.xml)与某些previous question with closer attribution to the problem.

I'm trying to confirm I can run my SBT project offline. I can, unless logback is one of my libraryDependencies. Why is logback triggering a problem? I've made a simple example consisting of just a build.sbt and a 'hello world' app...

build.sbt with a bunch of random dependencies to prove the point:

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/ inside my project, just to be sure
2. Ensure connected to the internet, and do sbt run. My hello world runs successfully
3. Disconnect from internet
4. sbt clean
5. sbt run. Build fails with logback as an unresolved dependency
6. Remove the logback dependency and sbt run again. Hello world runs.

This is the error from step 5:

Update:

Using the last command in SBT there is a lot of debug info for dependency resolution. Here's an example of Akka resolving successfully:

Here's the failure for Logback:

[warn] ==== public: tried
[warn]   http://repo1.maven.org/maven2/ch/qos/logback/logback-classic/1.1.1/logback-classic-1.1.1.pom

I can confirm the following files in the cache (not the '~/.ivy/local' folder):

~/.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

解决方案

When I try it, the file is indeed resolved from ~/.ivy2/cache. I have no ~/.ivy2/local because I do not publish locally. Is it possible that you have an ivysettings.xml file (on Linux, try locate ivysettings.xml) that is messing with some Ivy cache attribute, like resolutionCacheDir? It would still be a mystery why you only have problems with that one jar....

UPDATE: This appears to be a regression in SBT 0.13.1; it worked in 0.13.0, and as the OP himself discovered (see his answer), it was fixed in 0.13.2.
