playframework - sbt 0.13.5 "URI has an authority component"错误，同时解决 Play 2.3.0 项目的依赖关系

Question

将我的项目升级到 Play Framework 2.3.0(结果是 sbt 0.13.5)后，当 sbt 首次尝试在全新的 Debian 安装上解析依赖项时，我遇到了多个“URI has an authority component”错误。例如:

[error] (*:update) sbt.ResolveException: unresolved dependency: org.slf4j#slf4j-api;1.7.6: several problems occurred while resolving dependency: org.slf4j#slf4j-api;1.7.6 {compile=[compile(*), master(*)], runtime=[runtime(*)]}:
[error]     several problems occurred while resolving dependency: org.slf4j#slf4j-parent;1.7.6 {}:
[error]     URI has an authority component
[error]     URI has an authority component
[error]     URI has an authority component
[error]     URI has an authority component
[error]     URI has an authority component

这似乎是只有 *-parent 依赖项的问题，并且在早期版本的 play 和 sbt 上没有表现出来。我能够在三个不同位置的三个独立服务器上进行复制，都使用提供的 .deb 并手动放置启动器 jar。

任何指导将不胜感激。

Answer 1

在我的情况下，问题与配置的解析器之一有关:

  val projectResolvers = Seq[Resolver](
    "Local Maven Repository" at "file://"+Path.userHome.asFile.toURI.toURL+".m2/repository/",
    ...
  )

查看最后一个命令的详细信息(因错误而失败)后，我在解析器列表中看到了以下内容:

[debug]     Local Maven Repository: file://file:/Users/aldo/.m2/repository

删除硬编码的“file://”解决了这个问题:

  val projectResolvers = Seq[Resolver](
    "Local Maven Repository" at ""+Path.userHome.asFile.toURI.toURL+".m2/repository/",
    ...
  )
