ant ftp 不下载子目录中的文件

Question

我正在尝试使用 ant 从 ftp 服务器下载子目录中的文件。确切的文件集是已知的。其中一些位于子目录中。Ant 似乎只下载根目录中的那些。如果我下载所有文件而不列出它们，它确实有效。

第一个 ftp 操作应该与第二个操作完全相同。相反，我得到“隐藏文件\\a\a.txt 假定不是符号链接(symbolic link)。”

有人知道这里出了什么问题吗？这是 ant FTP 任务中的错误吗？

<?xml version="1.0" encoding="utf-8"?>
<project name="example" default="example" basedir=".">
    <taskdef name="ftp" 
    classname="org.apache.tools.ant.taskdefs.optional.net.FTP" />

    <target name="example">

        <!-- doesn't work -->
        <ftp action="get" verbose="true"
        server="localhost" userid="example" password="example" 
        remotedir="">
            <fileset dir="downloads" casesensitive="false" 
            includes="a/a.txt,a/b/ab.txt,c/c.txt" />
        </ftp>

        <!-- works (but requires multiple ftp tasks) -->
        <ftp action="get" verbose="true"
        server="localhost" userid="example" password="example"
        remotedir="a">
            <fileset dir="downloads" casesensitive="false" 
            includes="a.txt,b/ab.txt" />
        </ftp>
        <ftp action="get" verbose="true"
        server="localhost" userid="example" password="example"
        remotedir="c">
            <fileset dir="downloads" casesensitive="false" 
            includes="c.txt" />
        </ftp>

    </target>

</project>

更新:我向 Commons Net jira 发布了一个关于这个的错误 https://issues.apache.org/jira/browse/NET-324

更新:我在 ant 错误报告系统中添加了错误报告 https://issues.apache.org/bugzilla/show_bug.cgi?id=49296

因为我需要它来工作，所以我做了这个解决方法。它似乎有效，但我对此并不完全满意。感觉不干净。
