通過用sbt和sbt-assembly創建一個胖罐子來解決eclipselink的相關性問題？

我嘗試用Scala和EclipseLink JPA爲我的項目創建一個帶有sbt和sbt-assembly插件的胖jar包，但彙編命令失敗，因爲eclipse.inf文件將發現兩次。通過用sbt和sbt-assembly創建一個胖罐子來解決eclipselink的相關性問題？

[error] C:\Users\u987\WebApps\gr\lib_managed\jars\org.eclipse.persistence\commonj.sdo\commonj.sdo-2.1.1.jar:META-INF/eclipse.inf

我build.sbt樣子：

import AssemblyKeys._ 

name := "TelegramReceiver" 

version := "0.1" 

scalaVersion := "2.10.3" 

retrieveManaged in ThisBuild := true 

libraryDependencies ++= Seq(
    "org.scalatest" % "scalatest_2.10" % "2.0" % "test", 
    "org.eclipse.persistence" % "eclipselink" % "2.5.1" 
)

我嘗試從SBT組件插件與mergeStrategy來解決問題，但它不工作。我使用sbt 0.13.1。

在此先感謝您的幫助！

您能否提供您的合併策略和期望結果的示例。你有'eclipse.inf'完全相同的內容，如果不是你想保留哪一個？ –

您可以添加到您設置的自定義合併策略是這樣的：

mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) => 
    { 
    case PathList("eclipse.inf") => MergeStrategy.rename // use any of the available strategies like `first` 
    case x => old(x) 
    }}

詳情請參閱this doc。

感謝您的快速回答。我試試這個：case PathList（「eclipse.inf」）=> MergeStrategy.first但收到相同的錯誤。我不確定PathList的內容是文件名嗎？ – Twistleton

你的文件不在jar的根目錄下：'case「META-INF/eclipse.inf」'或者'case PathList（「META-INF」，「eclipse.inf」）'應該會更好。 – gourlaysama

非常感謝，阿列克謝伊茲麥洛夫和gourlaysama - 你拯救了我的一天。 – Twistleton
