Question

我尝试使用sbt程序集创建一个胖jar，我收到以下错误：

[error] (*:assembly) deduplicate: different file contents found in the following:

[error] C:\Documents and Settings\kp\.ivy2\cache\org.eclipse.persistence\commonj.sdo\jars\commonj.sdo-2.1.1.jar:META-INF/eclipse.inf

我的依赖是

Seq(
  "com.typesafe.akka" %% "akka-actor" % "2.3.15",
  "org.eclipse.persistence" % "eclipselink" % "2.6.2" % "provided" , 
  "org.scalikejdbc" %% "scalikejdbc" % "2.3.5",
  "org.scalaz" %% "scalaz-core" % "7.2.5"
)

问题的原因似乎是commonj.sdo-2.1.1.jar

Answer 1

如果相同的路径文件有不同的内容，则sbt-assembly会抛出错误。

您可以通过选择合并策略来避免或解决此错误。

在build.sbt

中添加以下代码

assemblyMergeStrategy in assembly := {
      case PathList("META-INF", "eclipse.inf") => MergeStrategy.last
      case x =>
        val oldStrategy = (assemblyMergeStrategy in assembly).value
        oldStrategy(x)
}

你应该看看https://github.com/sbt/sbt-assembly#merge-strategy

Answer 2

您需要做的是定义程序的合并策略。
