搖籃無法編譯基本斯卡拉項目

我似乎無法得到gradle這個正確編譯一個簡單的斯卡拉項目。該目錄是這樣的：搖籃無法編譯基本斯卡拉項目

. 
├── build.gradle 
└── src 
    └── Main.scala

的build.gradle很簡單：

apply plugin: 'scala' 

sourceSets { 
    main { 
     scala { 
      srcDir 'src' 
     } 
    } 
}

它失敗，這個迷人的小錯誤：

您還沒有宣佈的Scala版本要使用的，如在文檔和示例。（該錯誤消息在即將到來的Gradle 1.4中得到修復。）

repositories { 
    mavenCentral() 
} 

dependencies { 
    scalaTools "org.scala-lang:scala-compiler:2.9.2" 
    compile "org.scala-lang:scala-library:2.9.2" 
}

補充說，現在我得到「無法找到方法斯卡拉（）的論點之後[org.scala- lang：scala-compiler：2.9.2]在根項目'grad'上「。 –

啊...'scalaTools' :-) –

權，這是'scalaTools'（固定）。 Gradle 1.4會從'compile'依賴性中自動推斷出來。 –

我在Gradle 2.1上遇到了這個問題。（雖然我沒有得到同樣的錯誤，谷歌發現這對我來說）。我有一個「產生的原因：：編譯失敗，因爲內部編譯器錯誤的;詳見錯誤輸出」錯誤，這並沒有告訴我什麼嘿。

我沒有看到anything on the documentation，以表明我需要使用scalaTools或類似的東西。

我結束了關閉基於螞蟻編譯使用類型安全編譯鋅代替

tasks.withType(ScalaCompile) { 
    scalaCompileOptions.useAnt = false 
}
