FTP 自动下载过程在 Windows 上不起作用

Question

我的脚本如下：

<?xml version="1.0" encoding="UTF-8"?>
<project name="Getting from FTP" default="info" basedir=".">

   <target name="info">
    <property name="testfolder" value="My\Test\Folder\Path" />
      <echo>Hello World - Welcome to Apache Ant!</echo>
      <echo>Java version: ${ant.java.version}</echo>
      <echo>Ant Version: ${ant.version}</echo>
      <echo>Base Dir: "${basedir}"</echo>
      <mkdir dir="${testfolder}\ant-test"/>
       <classpath>
            <fileset dir="${basedir}" includes="*.jar" />
      </classpath>
      <ftp action="get"
        server="my.server.location.somewhere"
        userid="username"
        password="password"
        remotedir="/path/on/my/server"
        verbose="yes"
        >
        <fileset dir="${testfolder}\ant-test">
            <include name="**\*" />
        </fileset>
    </ftp>
   </target>
</project>

我正在 eclipse 上编写文件，并将 commons-net-3.3.jar 文件放在我的工作区文件夹中。这里是 AutomateDownload。但是，当我运行脚本时，出现此错误：

Buildfile: mydrive\on_server\my_workspace\ftpauto\AutomateDownload\build.xml
info:
     [echo] Hello World - Welcome to Apache Ant!
     [echo] Java version: 1.8
     [echo] Ant Version: Apache Ant(TM) version 1.9.4 compiled on April 29 2014
     [echo] Base Dir: "mydrive\on_server\my_workspace\ftpauto\AutomateDownload"

BUILD FAILED
mydrive\on_server\my_workspace\ftpauto\AutomateDownload\build.xml:11: Problem: failed to create task or type classpath
Cause: The name is undefined.
Action: Check the spelling.
Action: Check that any custom tasks/types have been declared.
Action: Check that any <presetdef>/<macrodef> declarations have taken place.

它在我的本地机器上运行良好，因为我将 .jar 文件保存在 ANT_HOME 的 lib 文件夹中。它运行完美。但现在当我在服务器机器上运行它时，我遇到了错误。有人能帮我解决我遇到的问题吗？你能详细告诉我，问题到底是什么吗？我为什么会遇到这种问题？谢谢 :)
