Why does Scala say that he cannot see the members of org.joda.time.Period?

Question

Im writing a Scala script that uses Joda Time 2.0.

When I try to run my script, I get errors like this:

error: value weeks is not a member of object org.joda.time.Period case "w" => Some(Period.weeks(windowSpecNum)) 

Im also getting a message for Period.minutes , Period.hours and Period.days .

This is really weird because I have no problem using other Joda time classes, and because this class works fine in Scala REPL:

 scala> Period.minutes(5) res0: org.joda.time.Period = PT5M 

I tried several workarounds:

 error: org.joda.time.Period does not have a constructor case "m" => Some(new Period().withMinutes(windowSpecNum)) 

and

 case "m" => Some(Minutes.minutes(windowSpecNum)) error: error while loading Minutes, Missing dependency 'class org.joda.convert.FromString', required by lib/joda-time-2.0.jar(org/joda/time/Minutes.class) 

which doesn't make sense since joda-convert-1.2.jar is in my classpath.

Just to make sure that I didn't do something dumb with types (Im new to Scala) I tried this: val p = Period.hours(5) and got the same error.

By this thread , perhaps the problem was that your class path did not include the Joda Time dependency on Joda Convert.
