設置配置屬性在REPL

Question

由於訪問：

的src /測試/斯卡拉/ NET/Main.scala

package net 

import com.typesafe.config.ConfigFactory 

object Main extends App { 
    override def main(args: Array[String]) { 
     val bar = ConfigFactory.load().getString("app.bar") 
     val bippy = ConfigFactory.load().getString("app.bippy") 
     println(s"bar: $bar | bippy : $bippy") 
    } 
} 

的src /測試/資源/ application.conf

app { 
    bar = ${?BAR} 
    bippy = ${?BIPPY} 
} 

我試圖設置BAR和BIPPY環境變量sbt：

>set envVars := Map("BAR" -> "bar!", "BIPPY" -> "bippy!")

然後，我在測試模式下打開REPL：

>test:console

scala> import net.Main 
import net.Main 

scala> Main.main(Array()) 
com.typesafe.config.ConfigException$Missing: No configuration setting 
    found for key 'app.bar' 

如何設置這些屬性REPL？

使用-Dconfig.file系統屬性
