Question

我有scala应用程序，并且使用了使用maven scala插件的pom.xml，我的应用程序使用scala readInt从命令行读取整数

该项目是在eclipse上构建的，当我使用eclipse运行scala应用程序时，它可以工作

当我尝试使用scala插件运行相同的应用程序时，它会卡住readInt

mvn scala:run  -DmainClass=run.readFromConsole

我错过了什么吗？

这是异常追踪

代码

object readFromConsole extends App {

  for (i <- 0 to 4) {
      println("Console Input " +i+ " "  + readInt )
  }

}

代码运行正常，使用scalac，scala甚至是eclipse scala应用程序，当我尝试从mvn scala应用程序运行它会抛出错误。

mvn clean compile scala:run  -DmainClass=run.readFromConsole

maven-scala-plugin卡在readInt scala上
