为什么我可以使用Scala REPL中的Java库而不是脚本？

这有效：

$scala -cp "lib/*"
Welcome to Scala version 2.9.1.final (Java HotSpot(TM) 64-Bit Server VM,Java 1.6.0_29).
Type in expressions to have them evaluated.
Type :help for more information.

scala> import org.joda.time._
import org.joda.time._

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

但这不是：

$scala -cp "lib/*" test.scala
/Users/avi/Dev/experiments/rollups/scala/test.scala:4: error: object joda is not a member of package org
import org.joda.time._
           ^
one error found

test.scala仅包含：

#!/usr/bin/env scala -cp lib/* -deprecation
!#

import org.joda.time._

Period.minutes(5)

这也行不通：

$scala -cp "lib/*" -e "import org.joda.time._"
/var/folders/c4/gh5y9_cx5bz8x_4wm060l_mm0000gn/T/scalacmd1248995773392653303.scala:1: error: object joda is not a member of package org
import org.joda.time._
           ^
one error found

这也不是因为在cp arg中使用*引起的：

$scala -cp lib/joda-time-2.0.jar:lib/joda-convert-1.2.jar -e "import org.joda.time._"
/var/folders/c4/gh5y9_cx5bz8x_4wm060l_mm0000gn/T/scalacmd5438658792813459030.scala:1: error: object joda is not a member of package org
import org.joda.time._
           ^
one error found

……这真是太疯狂了,因为这是我上次在这个项目上工作的时间,仅仅一两天前！而现在它不起作用了,我想我肯定已经改变了一些东西,但说实话,我想不出它会是什么.

救命！
