为什么我的sbt项目依赖不起作用？(坚持试图远程获取它)

Question

我想在sbt项目中为Scala.js和Snap.svg建立桥梁,但也包括桥梁的演示代码.

当做demos/compilesbt开始说它无法解决依赖.看起来它正试图到达桥梁,好像它是一个公开的外部项目,但它就在这里,它编译.

我究竟做错了什么？

删除特定于发布的文件似乎没有带来变化.

目录结构:

??? build.sbt
??? project
?   ??? (PublishToBintray.scala)
?   ??? build.properties
?   ??? build.sbt
?   ??? project
?   ?   ??? ...
?   ??? target
?   ?   ??? ...
??? (publishing.sbt)
??? scalajs_demos
?   ??? main
?   ?   ??? scala
?   ?       ??? clock.scala
?   ??? target
?       ??? ...
??? src
?   ??? main
?       ??? scala
?           ??? org
?               ??? scalajs
?                   ??? snapsvg
?                       ??? SnapSvg.scala
?                       ??? package.scala
??? target
    ??? ...

build.sbt:

scalaJSSettings

name := "Scala.js Snap.svg"

normalizedName := "scalajs-snapsvg"

version := "0.01"

organization := "org.scala-lang.modules.scalajs"

scalaVersion := "2.11.1"

crossScalaVersions := Seq("2.10.4", "2.11.1")   // note: not tested with 2.10.x

libraryDependencies +=
  "org.scala-lang.modules.scalajs" %%% "scalajs-dom" % "0.6"   // TBD: probably need it, just like jQuery bridge does

ScalaJSKeys.jsDependencies +=
  "org.webjars" % "Snap.svg" % "0.3.0" / "snap.svg.js"

homepage := Some(url("http://snapsvg.io/"))

licenses += ("Apache 2.0", url("https://github.com/adobe-webplatform/Snap.svg/blob/master/LICENSE"))

//---
// bridge (main) project
//
lazy val bridge = project.in( file(".") )

//---
// demos project
//
lazy val demos = project.in( file("scalajs_demos") ).dependsOn(bridge)

sbt出了什么问题:

还有一件事project/plugins.sbt:

addSbtPlugin("org.scala-lang.modules.scalajs" % "scalajs-sbt-plugin" % "0.5.0")

您的问题的根本原因是bridge项目使用scalaVersion := "2.11.1"(由您指定build.sbt,但您的demos项目使用默认值scalaVersion(在sbt 0.13,IIRC中为2.10.2).dependsOn当尝试将项目与不同的scalaVersions关联时,关系会变得混乱.请参阅此问题:https://github.com/sbt/sbt/issues/1448

您可能认为scalaVersion := "2.11.1"在根build.sbt中将适用于所有子项目.但事实并非如此,它只适用于根据.(此处bridge)的子项目.您还必须将此设置(以及您希望共享的其他设置)指定为settings()方法demos或scalajs_demos/build.sbt文件的参数.
