Question

我想在我的ANT命令中使用FTP标记从FTP位置接收文件。为了实现这一点，我在我的ANT的lib文件夹中复制了jakarta-oro-2.0.8.jar和apache-commons-net.jar。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？

Answer 1

ANT 1.6.5是一个非常古老的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>

bootstrap目标将缺少的ftp任务依赖项安装到ANT将在下次运行时使用的位置。

由于未解析的oro依赖性，ANT FTP构建命令失败
