Question

import org.apache.tools.ant.Project

object HelloWorld {
   def main(args: Array[String]) {
      println("Hello, world!")
   }
}

I tried to run this code using following command:

java -cp D:\tools\apache-ant-1.7.0\lib\ant.jar;D:\tools\scala-2.9.1.final\lib\scala-compiler.jar;D:\tools\scala-2.9.1.final\lib\scala-library.jar -Dscala.usejavacp=true scala.tools.nsc.MainGenericRunner D:\test\scala\ant.scala

There is following error:

D:\test\scala\ant.scala:1: error: object apache is not a member of package org
import org.apache.tools.ant.Project
           ^
one error found

What is wrong?

UPDATE:
As I can see it is impossible to import any org.xxx package.
The same problem with javax.xml.xxx package.

D:\test\test2.scala:2: error: object crypto is not a member of package javax.xml
import javax.xml.crypto.Data
                 ^
one error found  

Actually I cannot import anything!

D:\test\test3.scala:3: error: object test is not a member of package com
import com.test.utils.ant.taskdefs.SqlExt
           ^
one error found

I experimented with scala.bat (uncommenting the echo of the final command line, see the line starting with echo "%_JAVACMD%" ...) and found that this should work:

java -Dscala.usejavacp=true -cp d:\Dev\scala-2.9.1.final\lib\scala-compiler.jar;d:\Dev\scala-2.9.1.final\lib\scala-library.jar scala.tools.nsc.MainGenericRunner -cp d:\Dev\apache-ant-1.8.2\lib\ant.jar D:\test\scala\ant.scala
