Question

当我按照Scalatra文档（http://www.scalatra.org/2.2/guides/deployment/standalone.html）的方式运行“assembly”命令时，我收到以下错误：

[trace] Stack trace suppressed: run last *:assembly for the full output.
[error] (*:assembly) deduplicate: different file contents found in the following:

这意味着什么，以及如何解决？

这是我的构建文件，合并策略设置为第一个：

Answer 1

首先，在build.scala中，每行之间不必有空行。

其次，sbt-assembly的设置需要成为项目设置的一部分，因此您必须将其包含在Seq(...)的某个位置。

第三，你的合并策略不会起作用，因为类型不正确，你通常不能先找到所有东西。你应该尝试类似的东西：

Seq(
  organization := Organization,
  name := Name,
  ....

  jarName in assembly := "scalatra_atmosphere_demo.jar",
  mergeStrategy in assembly <<= (mergeStrategy in assembly) { (old) =>
    {
      case PathList(xs @ _*) if xs.last endsWith ".html" => MergeStrategy.first
      case x => old(x)
    }
  }
)

Scalatra独立部署无法创建程序集
