确定非托管依赖库的作用域sbt-assembly

Question

我正在尝试从我的主项目中确定一个非托管依赖库的范围。以下是场景

我在名为coinprism-api-assembly-1.2.jar的lib文件夹中有一个未管理的依赖项，该文件夹包含以下Build.scala文件：

  1 import sbt._
  2 import Keys._
  3 object CoinPrismBuild extends Build {
  4 
  5   val appName = "coinprism-api"
  6   val appV = "1.2"
  7   val scalaV = "2.11.2"
  8   val akkaV = "2.3.6"
  9   val sprayV = "1.3.2"
 10 
 11   val appDependencies = Seq(
 12     "com.typesafe.akka"   %%  "akka-actor"    % akkaV  withSources() withJavadoc(),
 13     "com.typesafe.akka"   %%  "akka-testkit"  % akkaV   % "test"  withSources() withJavadoc(),
 14     "io.spray"            %%  "spray-client"     % sprayV  withSources() withJavadoc(),
 15     "io.spray" %% "spray-can" % sprayV  withSources() withJavadoc(),
 16     "io.spray" %% "spray-routing" % sprayV  withSources() withJavadoc(),
 17     "io.spray" %%  "spray-json" % "1.3.1" withSources() withJavadoc(),
 18     "io.spray" %% "spray-testkit" % sprayV % "test" withSources() withJavadoc(),
 19     "org.scalatest" %% "scalatest" % "2.2.4" % "test" withSources() withJavadoc(),
 20     "joda-time" % "joda-time" % "2.7"
 21   )
 22 
 23 
 24   lazy val root = Project(appName, base=file(".")).settings(
 25     scalaVersion := scalaV,
 26     version := appV,
 27     libraryDependencies ++= appDependencies
 28   )
 29 
 30 }

我正在尝试组装的项目具有以下build.sbt文件：

import AssemblyKeys._    

name := "suredbits-core" 

version := "2.13.0" 

scalaVersion := "2.11.4" 

resolvers += Resolver.mavenLocal

organization := "com.suredbits.core"

libraryDependencies ++= {  
    val sprayV = "1.3.2"
    val akkaV = "2.3.8" 
    Seq(
    "org.scalatest" % "scalatest_2.11" % "2.2.0",
    "io.spray"            %%  "spray-can"     % sprayV % "provided"  withSources() withJavadoc(),
    "io.spray"            %%  "spray-routing" % sprayV % "provided"  withSources() withJavadoc(),
    "io.spray"            %%  "spray-testkit" % sprayV  % "test"  withSources() withJavadoc(),
    "com.typesafe.akka"   %%  "akka-actor"    % akkaV % "provided" withSources() withJavadoc(),
    "com.typesafe.akka"   %%  "akka-testkit"  % akkaV   % "test" withSources() withJavadoc(),
    "org.specs2"          %%  "specs2-core"   % "2.4.7-scalaz-7.0.6" % "test" withSources() withJavadoc(),
    "org.scalactic"             %%  "scalactic" %   "2.2.1" % "test" withSources() withJavadoc(),
    "io.spray" %%  "spray-json" % "1.3.0" withSources() withJavadoc(),
    "info.blockchain" % "api" % "1.0.1", 
    "com.github.nscala-time" %% "nscala-time" % "1.6.0" withSources() withJavadoc() ,
    "com.typesafe.slick" %% "slick" % "2.1.0" withSources() withJavadoc(),
    "com.typesafe.slick" %% "slick-testkit" % "2.1.0" % "test" withSources() withJavadoc(),
    "com.novocode" % "junit-interface" % "0.10" % "test" withSources() withJavadoc(),
    "postgresql" % "postgresql" % "9.1-901.jdbc4" % "test" withSources() withJavadoc(),
    "org.postgresql" % "postgresql" % "9.2-1003-jdbc4" withSources() withJavadoc(),
      "org.bitcoinj" % "bitcoinj-core" % "0.12" withSources() withJavadoc() ,
    "org.slf4j" % "slf4j-api" % "1.7.5",
    "org.slf4j" % "slf4j-simple" % "1.7.5"
  )
}               

testOptions += Tests.Argument(TestFrameworks.JUnit, "-q", "-v", "-s", "-a")

parallelExecution in Test := false

logBuffered := false

scalacOptions ++= Seq("-unchecked", "-deprecation", "-feature")

scalacOptions ++= Seq("-Xmax-classfile-name", "255")

scalacOptions in (Compile,doc) ++= Seq("-groups", "-implicits")

这是我在切换到sbt-assembly版本0.11.2后得到的错误消息。

那么，如何从与suredbits-core内部的jar冲突中排除coin-prism-api jar中的依赖项呢

Answer 1

据我所知，您包含的其中一个库包含一个"xml“scala库，并且在您的项目中也使用该库(直接或通过依赖)

除了使用这个库的两个不同版本之外，一切都应该很好。sbt-assembly应该使用哪个版本的库？如果它选择一个版本，那么使用其他版本的模块将无法工作。

在您的jar中，同一个库不能有两个不同的版本。
