Question

在我的plugins.sbt文件中，我有

scalaVersion := "2.10.0"

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

addSbtPlugin("play" % "sbt-plugin" % "2.1")

当我尝试运行sbt时，除其他外，我得到了

[warn] ==== Typesafe repository: tried
[warn]   http://repo.typesafe.com/typesafe/releases/play/sbt-plugin_2.10_0.12/2.1/sbt-        plugin-2.1.pom

[warn]
sbt.ResolveException: unresolved dependency: play#sbt-plugin;2.1: not found

为什么SBT找不到该插件？我也尝试过addSbtPlugin("play" % "sbt-plugin" % "2.1-RC1")类似的结果。

Answer 1

问题包括plugins.sbt文件中的scalaVersion设置。这会导致sbt在应该实际搜索sbt-plugin_2.9.2_0.12时在存储库中搜索sbt-plugin_2.10.0_0.12。

我不确定在plugins.sbt文件中指定scalaVersion背后的语义，但也许它声明了SBT正在运行的Scala版本。

以下是Play 2.1 sbt-plugin文件的链接：http://repo.typesafe.com/typesafe/simple/ivy-releases/play/sbt-plugin/scala_2.9.2/sbt_0.12/2.1-RC1/srcs/

Answer 2

根据文件，在project/plugins.sbt：

中添加此内容

addSbtPlugin("play" % "sbt-plugin" % "2.1.0")

更改project/build.properties

sbt.version=0.12.2

为什么SBT找不到Play 2.1插件？
