Scala Bash test scripts

Question

I'm trying to write a simple batch script to test my Scala program. The script should be something like this:

#!/bin/bash
scala ./build/classes/MyClass "../../res/some_file.txt"

This returns:

Exception in thread "main" java.lang.RuntimeException: Cannot figure out how to run target: ./build/classes/MyClass

If I'm in the classes directory running:

#!/bin/bash
scala MyClass "../../res/some_file.txt"

works as expected.

What am I doing wrong here?

You cannot pass the file name of a class -- you have to pass the class name, and it has to be in the classpath. So, instead, try this:

#!/bin/bash
scala -cp ./build/classes MyClass "../../res/some_file.txt"
