How to add external library to the classpath in scala's interpreter?

I'm trying to reference some classes in the Scala Interpreter that were writen and compiled using Eclipse. Eclipse stores compiled Java byte code in a folder {workspace}/myProject/bin. Is there some command which will add this folder to the classpath used by the Scala Interpreter?

Maybe scala.bat should be edited or parameterized with some argument?

From stackoverflow

• You can edit scala.bat, or rather make a copy to leave the original unchanged.

  You will probably want to use call :add_cpath "..." to add it, as is used somewhere in that batch file.

• Use the -classpath or -cp flags when launching the interpreter:

  scala -cp /path/to/classfiles
