命令行参数不适用于sbt-assembly jar

Question

我试图将命令行参数传递给我创建的JAR sbt-assembly.这些-Dconfig.file=application.conf都不是-Dconfig.trace=loads

我的确切命令是

java -jar googleScraper-assembly-0.0.1.jar -Dconfig.trace=loads -Dconfig.resource=application.conf

这是我的build.sbt

lazy val googleScraper = project.in(file("google-data-scraper"))
  .settings(commonSettings:_*)
  .settings(
    version := "0.0.1",
    assemblyMergeStrategy in assembly := {
      case m if m.toLowerCase.endsWith("manifest.mf") => MergeStrategy.discard
      case m if m.toLowerCase.matches("meta-inf.*\\.sf$") => MergeStrategy.discard
      case "log4j.properties" => MergeStrategy.discard
      case m if m.toLowerCase.startsWith("meta-inf/services/") => MergeStrategy.filterDistinctLines
      case "reference.conf" => MergeStrategy.concat
      case "application.conf" => MergeStrategy.concat
      case _ => MergeStrategy.first
    },
    libraryDependencies ++= Seq(
      "com.typesafe" % "config" % "1.3.0",
      "com.typesafe.play" % "play_2.11" % "2.3.9",
      "com.typesafe.play" % "play-ws_2.11" % "2.3.9",
      "com.ning" % "async-http-client" % "1.8.15"
    ),
    fork in run := true
  )
  .dependsOn("util")
  .dependsOn("core")

事实证明,在-jar之前放置参数会产生不同的结果.这现在有效:

java -Dconfig.trace=loads -Dconfig.resource=blah.conf -jar googleScraper-assembly-0.0.1.jar

但现在加载表明应用程序正在尝试从JAR中加载新配置.如何让它完全从外部加载(绝对路径不起作用)？

(从评论中提取答案)

JVM选项(如-D)必须在-jar之前

config.file是外部文件,config.resource是类路径上的资源.
