How to import an user defined package into scala REPL automatically when scala REPL is started?

Question

When scala REPL starts some default packages like scala.lang._ , scala.Predef are automatically available.Suppose I have my own package like com.raghhuraamm.rUtils._

How to import this package automatically when REPL starts? Is there a way or I just have to type "import com.raghhuraamm.rUtils._ " every time I start scala REPL?

@ChaitanyaWaikar Neither is this question about SBT, nor do the linked answers say anything about `import`ing packages automatically. — Andrey Tyukin, Jul 12 '18 at 08:58

If you could use sbt console to launch the REPL, you can create a build.sbt containing this line:

initialCommands in Compile in console += "import com.raghhuraamm.rUtils._"

Create a script (myPreload.scala, say) that contains all the imports that you want:

// in myPreload.scala
import com.raghhuraamm.rUtils._

Assuming that the classes are packaged in my.jar, start the scala repl as follows:

scala -cp path/to/my.jar -i some/other/path/to/myPreload.scala
