Question

我有以下Scala（2.10.1）脚本：

#!/bin/bash

export CLASSPATH=${WORKSPACE}/build/classes/main:${WORKSPACE}/build/libs/setter-for-catan.jar

exec ${SCALA_HOME}/bin/scala "$0" "$@" 2>&1
!#

import sfc.board.SmallBoard

和

$ cd ${WORKSPACE}
$ find build/classes/main -name 'SmallBoard*.class'
build/classes/main/sfc/board/SmallBoard$$anonfun$1.class
build/classes/main/sfc/board/SmallBoard$$anonfun$2.class
build/classes/main/sfc/board/SmallBoard$$anonfun$3.class
build/classes/main/sfc/board/SmallBoard$$anonfun$4.class
build/classes/main/sfc/board/SmallBoard$$anonfun$5.class
build/classes/main/sfc/board/SmallBoard$$anonfun$6.class
build/classes/main/sfc/board/SmallBoard$.class
build/classes/main/sfc/board/SmallBoard.class
$ jar tvf build/libs/setter-for-catan.jar | grep SmallBoard

  3722 Sun Jun 30 20:40:54 EDT 2013 sfc/board/SmallBoard.class

然而脚本没有找到sfc包而不是类：

$ ./setter-for-catan.scala 
./setter-for-catan.scala:10: error: not found: object sfc
import sfc.board.SmallBoard
       ^
one error found

发生了什么以及需要采取哪些措施来解决问题？

Answer 1

使用scala -cp ${CLASSPATH}，而不是scala -classpath ${CLASSPATH}。

尽管设置了CLASSPATH或使用-classpath选项，为什么Scala脚本找不到类？
