Question

我尝试用scala和EclipseLink JPA为我的项目创建一个带有sbt和sbt-assembly插件的胖jar，但是程序集命令失败了，因为eclipse.inf文件会找到两次。

> assembly
[info] Including from cache: commonj.sdo-2.1.1.jar
[info] Including from cache: javax.persistence-2.1.0.jar
[info] Including from cache: scala-library.jar

[error] (*:assembly) deduplicate: different file contents found in the following:
[error] C:\Users\u987\WebApps\gr\lib_managed\jars\org.eclipse.persistence\javax.persistence\jav    ax.persistence-2.1.0.jar:META-INF/eclipse.inf 
[error] C:\Users\u987\WebApps\gr\lib_managed\jars\org.eclipse.persistence\commonj.sdo\commonj.sdo-2.1.1.jar:META-INF/eclipse.inf

我的build.sbt看起来像：

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" 
)

我尝试使用sbt程序集插件中的mergeStrategy来解决问题，但它不起作用。我使用sbt 0.13.1。

提前感谢您的帮助！

您可以在设置中添加如下自定义合并策略：

  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)
  }}

有关详细信息，请参阅this doc。

通过使用sbt和sbt-assembly创建一个胖jar来解决eclipselink的依赖关系？
