sbt 找不到 scripted-sbt 依赖项

Question

我正在为我的一个项目使用 scripted sbt 插件，它一直运行良好，但最近突然停止工作，原因不明。这是一个失败的示例设置：

# project/plugins.sbt
libraryDependencies += "org.scala-sbt" % "scripted-plugin" % sbtVersion.value

# build.sbt
scalaVersion := "2.11.6"

scriptedSettings

# project/build.properties
sbt.version=0.13.5

当我执行 sbt update 时，我看到了以下内容。请注意，它下载 scripted-plugin 但找不到 scripted-sbt。直到最近这一切都很好，只是有点停止了。有什么想法吗？

看起来脚本插件只能在 sbt-plugins 存储库中找到。这似乎只有在 sbtPlugin 设置为 true 时才添加。

对您的示例进行以下更改为我提供了一个解决方案：

#build.sbt 
sbtPlugin := true

scalaVersion := "2.11.6"

scriptedSettings

输出如下：

sbt update

请注意，我也用 sbt 0.13.8 尝试过这个并且有完全相同的问题和相同的结果。

编辑：如果设置 sbtPlugin := true 对于这个特定的应用程序没有意义，您可以将 resolvers += Resolver.typesafeIvyRepo("releases") 添加到主 build.sbt 以获得相同的结果。

EDIT2：这也可能是一个问题：resolvers not shared to dependent sbt projects?
