为什么 sbt 因 play-geojson 的未解决依赖关系而失败？答案

【问题标题】：Why does sbt fail with UNRESOLVED DEPENDENCIES for play-geojson?为什么 sbt 因 play-geojson 的未解决依赖关系而失败？
【发布时间】：2015-02-26 00:36:59
【问题描述】：

我正在使用 GeoJSON 编写一个播放框架应用程序，我打算使用 play-gejson。当我按照指示将依赖项添加到build.sbt 时，激活器找不到它。

这是我应该补充的内容：

"com.typesafe.play.extras" %% "play-geojson" % "1.0.0"

有什么想法吗？

更新

我还尝试添加以下解析器 - 无济于事。

resolvers += "Typesafe repository" at "http://repo.typesafe.com/typesafe/releases/"

这是错误：

【问题讨论】：

标签： playframework-2.0 sbt typesafe-activator

【解决方案1】：

似乎README 自最新版本以来尚未更新。 1.0.0 仅为 Scala 2.10 而不是 2.11 构建。但是 Scala 2.10 和 2.11 已经交叉构建了 1.1.0。只需将版本升级到 1.1.0：

"com.typesafe.play.extras" %% "play-geojson" % "1.1.0"

（如果出于某种原因需要 1.0.0，也可以使用 Scala 2.10）

【讨论】：

另外——版本升级后就不需要添加解析器了。
