我想在我的 ANT 命令中使用 FTP 标签从 FTP 位置接收文件。为了实现这一点，我复制jakarta-oro-2.0.8.jar并apache-commons-net.jar在我的 ANT 的 lib 文件夹中。运行命令时出现以下错误： java.lang.Error: Unresolved compilation问题：

为什么 Ant 无法导入 ORO 依赖项？

ANT 1.6.5 是一个非常旧的 ANT 版本。以下示例使用 ANT 1.9.0 进行了测试：

<project name="demo" default="build">

   <target name="bootstrap">
      <mkdir dir="${user.home}/.ant/lib"/>
      <get dest="${user.home}/.ant/lib/commons-net.jar" src="http://search.maven.org/remotecontent?filepath=commons-net/commons-net/3.3/commons-net-3.3.jar"/>
      <get dest="${user.home}/.ant/lib/oro.jar" src="http://search.maven.org/remotecontent?filepath=oro/oro/2.0.8/oro-2.0.8.jar"/>
   </target>

   <target name="build">
      <ftp server="ftp.apache.org" userid="anonymous" password="me@myorg.com">
         <fileset dir="htdocs/manual"/>
      </ftp>
   </target>

</project>

引导目标将缺少的 ftp 任务依赖项安装到 ANT 下次运行时将使用的位置。
