How to fire up Scala interpreter with ScalaCheck in the classpath in Ubuntu 11.10?

Question

Scala is installed and working fine.
scalacheck.jar is placed in the /bin .
I used the following command

$ scala -cp scalacheck.jar

After that, when i tried the below command,

scala> import org.scalacheck.Prop.forAll

I got the following error.

<console>:7: error: object scalacheck is not a member of package org
   import org.scalacheck.Properties
              ^

I might have done some mistake in using scalacheck, please correct me and give the proper commands so that I can able to work with scalacheck in Ubuntu in interpreter mode.

Answer 1

Putting executable on the path isn't the same as jar being on the classpath, so your jar being in /bin didn't change anything.

Just use:

scala -cp path_to_your.jar 

and you should be fine.

If for example, your scalachek.jar is in /bin then use:

scala -cp /bin/scalacheck.jar

edit:

Putting jars in /bin probably isn't the best idea.

You can use it like this:
