scala - Getting started with a SBT project -

i have been given skeleton sbt project work on. directory structure follows:

|-- build.sbt |-- project |   |-- build.properties |   |-- plugins.sbt |   |-- project |   `-- target |-- readme.md `-- src     |-- main     |   `-- scala     |       `-- com     |           `-- app-name     |               |-- domain     |               |-- exception     |               |-- repository     |               `-- util     `-- test         `-- scala `-- vagrantfile 

the instructions create app entry point should take single command line argument , run logic.

i have managed simple "hello world" sbt project working i'm new scala/sbt. place entry point , how can accept command line argument?

the root folder source files src/main/scala.

parameters referenced using args array within entry point object.

the entry point object under source tree extends app. since hello world example , you're getting started, i'd drop right root of sources (src/main/scala/myapp.scala).

something this:

object myapp extends app {     println(args.length match {         case 0 => "you passed in no arguments!"         case 1 => s"you passed in 1 argument, ${args(0)}"         case x => s"you passed in $x arguments! are: ${args.mkstring(",")}"     }) } 

to run app, issue sbt run command in project root. run parameters, sbt run "arg1".
