为什么我的sbt项目依赖不起作用？ (坚持试图远程获取它)

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.

在做demos / compile时,sbt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.

sbt出了什么问题：

还有一件事,项目/ plugins.sbt：

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

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

你可能认为root build.sbt中的scalaVersion：=“2.11.1”将适用于所有子项目.但事实并非如此,它只适用于根植于的子项目. (这里,桥).您还必须将此设置(以及您希望共享的其他设置)指定为演示的settings()方法的参数,或者在scalajs_demos / build.sbt文件中指定.
