I am new to Scala. I have installed Scala 2.9 from the repository on Ubuntu 12.04. My Scala REPL is working perfect. I have compiled scala file perfectly but when I tried to run a simple script file [println ("Hello")] with -------> "scala Test.scala" I got the following error.
Exception in thread "main" java.lang.RuntimeException: Cannot figure out how to run target: Test.scala
at scala.sys.package$.error(package.scala:27)

Please help me to get rid of this error. Thanking you in advance.

what are the contents of Test.scala?

I tried this:

then ran Test.scala using scala Test.scala and it works fine.

PS: I tried this on Windows, but I believe the platform shouldn't really matter.

I’ve looked at a lot of different solutions, and in my humble opinion Aspose is the way to go. Here’s the link: http://aspose.com
