在阅读了程序集插件的wiki后,我在build.scala文件中添加了合并策略.似乎它不起作用.我不确定它是否正确修复.有人可以建议我正确的策略.

下面是我在build.scala文件中的代码：

mergeStrategy in assembly <<= (mergeStrategy in assembly) {
      (old) => {
        case "about.html" => MergeStrategy.discard
        case "logback.xml" => MergeStrategy.first //case PathList("logback.xml") => MergeStrategy.discard
        case x => old(x)
      }
    }

我已根据此doc：Standalone deployment of Scalatra servlet编写了与我的应用程序的插件集成

我尝试了不同的策略,如MergeStrategy.rename和MergeStrategy.deduplicate.但没有任何作用..
寻求帮助……

解决方法

您的MergeStrategy看起来是正确的.唯一未处理的冲突是码头罐中的“about.html”,所以案例“about.html”=> MergeStrategy.discard应该这样做.

如果您仍然收到错误,我怀疑在程序集设置中重新连接mergeStrategy要么没有进入,要么进入错误的顺序.确切知道的唯一方法是看看你的Build.scala. @Stefan Ollinger对您的链接问题的回答例如设置项目如下：

lazy val project = Project("myProj",file(".")).
  settings(mySettings: _*).
  settings(myAssemblySettings:_*)

如果可能,你可以在gist发布你的Build.scala吗？
