Gradle + PlayFramework：無法解析源依賴

Question

我在Gradle 2.7中使用新的Play Framework支持。具有諷刺意味的是，Play 2.3.x明確依賴org.scala-sbt:io:0.13.8。

搖籃能夠解決從類型安全的存儲庫JAR（沒有來源，就在班）如果我添加

model { components { play { platform play: "2.3.7", scala: "2.10", java: "1.7" } } } repositories { maven { name "typesafe-maven-release" url "https://repo.typesafe.com/typesafe/maven-releases" } ivy { name "typesafe-ivy-release" url "https://repo.typesafe.com/typesafe/ivy-releases" layout "ivy" } } dependencies { play group: "org.scala-sbt", name: "io", version: "0.13.8", classifier: "jar", configuration: "compile" }

但它似乎無法解決io-sources.jar。我得到這個：

FAILURE: Build failed with an exception.

• 出了什麼問題： 執行失敗的任務 '：runPlayBinary'。

  Could not find io-sources.jar (org.scala-sbt:io:0.13.8). Searched in the following locations: https://repo.typesafe.com/typesafe/ivy-releases/org.scala-sbt/io/0.13.8/srcs/io.jar

我其實並不關心這些來源，我只是想避免這種運行時異常運行時gradlew runPlay

Execution exception [RuntimeException: java.lang.NoClassDefFoundError: sbt/Path$]

有什麼建議？我似乎無法弄清楚如何排除或解決源依賴。

A類搖籃dev的回答對Gradle forums

TL我的問題; DR - Gradle/Play bug具體到2.3.7，可以通過使用解決

repositories { 
    ivy { 
     url "https://repo.typesafe.com/typesafe/ivy-releases/" 
     layout "pattern", { 
      ivy "[organisation]/[module]/[revision]/ivys/ivy.xml" 
      artifact "[organisation]/[module]/[revision]/jars/[artifact].[ext]" 
     } 
    } 
} 

在我的情況下，你pgrading Play 2.3.9修復了我的問題。

Answer 2

我遇到了與Play 2.4和Gradle 2.7相同的RuntimeException（NoClassDefFound sbt/Path $）。在我的情況下，根本問題是沒有正確定義所有的存儲庫（不包括typesafe-ivy-> sbt-io沒有解決 - >我以爲我需要說明sbt-io-dependency->錯誤的sbt-io導致提到例外...）。

我建議您添加jcenter（）作爲存儲庫，刪除sbt的顯式依賴項，並在build.gradle中聲明播放版本。作爲一個例子我的工作gradle.build：

plugins { 
id 'play' 
} 
dependencies { 
repositories { 
    jcenter() 
    maven { 
    name "typesafe-maven-release" 
    url "https://repo.typesafe.com/typesafe/maven-releases" 
    } 
    ivy { 
    name "typesafe-ivy-release" 
    url "https://repo.typesafe.com/typesafe/ivy-releases" 
    layout "ivy" 
    } 
} 
play 'com.typesafe.play:play-jdbc_2.11:2.4.3' 
[...other dependencies - but not "org.scala-sbt"!] 
} 

model { 
components { 
    play { 
    platform play: '2.4.3', scala: '2.11' 
    injectedRoutesGenerator = true 
    } 
} 
} 

在你的情況下，最後一部分應該是：

model { 
components { 
    play { 
    platform play: '2.3.7', scala: '2.10' 
    } 
} 
}
