Question

我提到了json4s-native 3.3.0但引用了3.3.0-SNAPSHOT。

在我的项目中，有3个模块（通用，读写）都有scala.sbt。

改变之前：

“org.json4s”%%“json4s-native”％Versions.Json4s％“编译”，

更改后:(更改了3个模块中的所有位置）

“org.json4s”%%“json4s-native”％“3.3.0”％“编译”，

我跑：

SBT

清洁

更新

错误：

我的销售buld.sbt 是：

我的阅读模块 build.sbt ：

libraryDependencies ++= Seq(
  "com.mycompany"         %% "myapp-core-read"            % myappsales.CoreVersion            % "compile", // disable using the Scala version in output paths and artifacts,
  "com.mycompany"         %% "myapp-core-write"           % myappsales.CoreVersion            % "compile",

    .inLibrary("play" % "play-iteratees_2.10" % "2.1-RC2")
)

assemblyMergeStrategy in assembly := {
  case "application.conf" => MergeStrategy.concat
  case path => MergeStrategy.defaultMergeStrategy(path)
}

//Make assembly a publishable artifact
artifact in (
  Compile, assembly) := {
  val art = (artifact in (Compile, assembly)).value
  art.copy(`classifier` = Some("assembly"))
}

addArtifact(artifact in (Compile, assembly), assembly)

为什么还在寻找SNAPSHOT版本？

Answer 1

这是调查此类问题的一种相当标准的方法。在 plugins.sbt

中

addSbtPlugin("net.virtual-void" % "sbt-dependency-graph" % "0.8.2")

然后转到sbt dependencyBrowseGraph，这将打开您的浏览器并转到一个页面，其中可以浏览包括被驱逐者在内的整个依赖关系图。现在找出SNAPSHOT来自哪里，并排除它。

为什么Scala要寻找SNAPSHOT版本？
