播放2.4遷移sbt錯誤

我試圖將我的播放應用程序從版本2.3.10遷移到2.4（我使用Java）。我遵循播放主頁上的遷移指南，但是發生了sbt錯誤。我到目前爲止所做的： - 將build.sbt中的scala版本更改爲2.11.6 - 將plug version.sbt中的play版本更改爲2.4.0 - 將build.properties中的sbt.version更改爲0.13。 8播放2.4遷移sbt錯誤

的build.sbt刷新我碰到下面的錯誤後：

看來，SBT無法找到子項目，但我不知道我可以解決這個錯誤。順便說一下，應用程序在2.3.10上無縫工作。

我希望有人能幫助我！提前致謝。

普萊舍看看這個問題的答案

Can't use sbt 0.13.7 with Play subprojects

它看起來非常相似。如果你有當前sbt版本0.13.5，那麼我很確定這是你的問題

就是這樣！非常感謝你！ – egcram

嘗試將這些添加到plugins.sbt file;

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

// The Play plugin 
addSbtPlugin("com.typesafe.play" % "sbt-plugin" % "2.4.3")

我建議你使用2.4.3如果你要升級你的Play版本，它應該是最新的。此外，按照這guideline，比你應該沒事。
