org.scala-sbt＃sbt; $ {{sbt.version}}：在現有項目中找不到

我從git複製了一個Play框架Scala項目，當我啓動命令$ Play時，出現此錯誤：

Getting org.scala-sbt sbt ${{sbt.version}} ...

我使用的播放2.1.0，SBT發射版本0.12.2（和Windows OS）

如何解決這個問題？

你有沒有嘗試運行SBT獨立？它可能看起來像sbt沒有妥善解決。 –

..或者檢查了這個線程？ http://stackoverflow.com/questions/16327123/error-module-not-found-org-scala-sbtsbtsbt-version –

我有這個問題。我不小心將'project /'添加到'.gitingore'。克隆之後，'project'目錄被省略，並且拋出了這個錯誤。 –
