Question

我正在使用sbt程序集尝试使用我们的应用程序并创建“一个大罐子”来部署它。

我遇到的问题是Play 2.1.2依赖于scala-stm 0.6而akka-transactor 2.1.4依赖于scala-stm 0.7。

我可以在SBT中运行应用程序而不会出现问题（以及Eclipse和IntelliJ）

我不清楚如何使用'sbt assembly'

解决此问题

这里有一些输出正好解释了我所看到的内容（剪掉一些内容）：

如果我查看依赖树，我会看到两个具有冲突依赖关系的东西（修剪了一堆东西）：

有关如何解决此依赖性问题的任何建议？

=========================编辑：添加更简单的例子================ =======

我决定尝试使用Play和Akka创建一个非常简单的应用程序。但是，我试图“组装”一个简单的Play应用程序并遇到问题。

这是我的project / plugins.sbt文件：

resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.9.1")

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.7.4")

addSbtPlugin("play" % "sbt-plugin" % "2.1.0")

这是我的项目/ Build.scala文件：

import sbt._
import Keys._
import play.Project._
import sbtassembly.Plugin._
import AssemblyKeys._



object ApplicationBuild extends Build {

        val appName = "dependencyExample"
        val appVersion = "1.0"

        val appDependencies = Nil
        val appSettings = Defaults.defaultSettings ++ assemblySettings ++ Seq(net.virtualvoid.sbt.graph.Plugin.graphSettings:_*)

        val main = play.Project( appName, appVersion, appDependencies, settings = appSettings)
}

这是我从'assembly'获得的输出

我仍然不清楚如何解决这个问题。我怀疑如果我能解决这个简单的测试问题，那么我可以解决Akka + Play问题。

===================编辑：完成同样事情的不同方式=================

我发现了一个'魔法'sbt命令。 'DIST'。这将应用程序打包为.zip文件，然后可以在任何安装了java的计算机上解压缩并运行。

以下是我们在课程上发现的一篇博文：
