解析器未共享给依赖的 sbt 项目？

在这个似乎涉及 xsbt-web-plugin 的奇怪情况下，我收到错误

unresolved dependency: play#play-json_2.10;2.2-SNAPSHOT: not found

当加载时server子项目。依赖项和正确的解析器在library子项目，其中server依赖于取决于。如果我不包含它就不会爆炸webSettings在服务器中，但我正在尝试在那里构建一个 .war 。

[根目录]/project/Build.scala

import sbt._
import Keys._

object MyBuild extends Build {
  lazy val root = Project("root", base = file(".")).aggregate(library,server)

  lazy val library = Project(id = "library", base = file("library"))

  lazy val server = Project(id = "server", base = file("server")).dependsOn(library)
}

[根]/project/plugins.sbt

// p.s. why do I need this here instead of [root]/server/project/plugins.sbt?
addSbtPlugin("com.earldouglas" % "xsbt-web-plugin" % "0.3.0")

[根]/库/build.sbt

scalaVersion := "2.10.1"

libraryDependencies += "play" %% "play-json" % "2.2-SNAPSHOT"

resolvers += "Mandubian repository snapshots" at "https://github.com/mandubian/mandubian-mvn/raw/master/snapshots/"

[根目录]/server/build.sbt

scalaVersion := "2.10.1"

seq(webSettings :_*)

您可以使用resolvers in ThisBuild += ...使解析器可用于构建的任何子项目。 （这将进入[root]/build.sbt.)
