回显文件集中的每个文件的大小、日期和时间

发布于 2024-11-07 02:52:23 字数 526 浏览 2 评论 0原文

我正在将 DOS 批处理文件转换为 Ant。在批处理文件的末尾，我使用 DOS dir 命令打印出复制的文件列表，包括大小、日期和时间。我想在 Ant 脚本的末尾做同样的事情。到目前为止，我已经：

<!-- LIST COPIED FILES -->
<target name="summary" depends="backup">
    <fileset id="zipfiles" dir="${dest}" casesensitive="yes">
        <include name="*.zip"/>
    </fileset>  

    <property name="prop.zipfiles" refid="zipfiles"/>
    <echo>${prop.zipfiles}</echo>       
</target>

如何修改上述内容以在单独的行上打印每个文件，并包含大小、日期和时间？

I'm converting a DOS batch file to Ant. At the end of the batch file, I print out a list of files copied including size, date and time using the DOS dir command. I would like to do the same at the end of the Ant script. So far I have:

<!-- LIST COPIED FILES -->
<target name="summary" depends="backup">
    <fileset id="zipfiles" dir="${dest}" casesensitive="yes">
        <include name="*.zip"/>
    </fileset>  

    <property name="prop.zipfiles" refid="zipfiles"/>
    <echo>${prop.zipfiles}</echo>       
</target>

How can I modify the above to print each file on a separate line, with size, date and time?

有一个基于外部任务套件的解决方案，称为 Ant Flaka。
使用 Ant Flaka，您可以从文件集中访问底层文件对象及其属性（名称、运行时间、大小..）。无需通过 apply/cmd

<project name="demo" xmlns:fl="antlib:it.haefelinger.flaka">
    <fl:install-property-handler />

    <!-- as fileset has no absolute pathnames we need
         path combined with pathconvert -->
    <path id="foobar">
        <fileset dir="/home/gilreb/Downloads">
            <include name="*.zip"/>
        </fileset>
    </path>

    <pathconvert property="zipfiles" refid="foobar"/>

    <!-- iterate over the listentries, get access to
         the underlying fileobject and echo its properties -->
    <fl:for var="f" in="split('${zipfiles}', ':')">
        <echo>
      #{  format('filename %s, last modified %tD, size %s bytes', f.tofile.toabs,f.tofile.mtime,f.tofile.size)  }
     </echo>
    </fl:for>

</project>

输出打开外部进程=

...  
   [echo]       filename /some/path/apache-ant-1.8.2-bin.zip, last modified 03/16/11, size 10920710 bytes
     [echo]      
     [echo]       filename /some/path/apache-ant-1.8.2-src.zip, last modified 03/16/11, size 8803388 bytes
     [echo]      
     [echo]       filename /some/path/apache-ant-antunit-1.1-bin.zip, last modified 04/17/11, size 70477 bytes
...

There is a solution based on an external Tasksuite called Ant Flaka.
With Ant Flaka you get access to the underlying fileobjects and their properties (name,mtime,size..) from your fileset. no need to open an external process via apply/cmd

<project name="demo" xmlns:fl="antlib:it.haefelinger.flaka">
    <fl:install-property-handler />

    <!-- as fileset has no absolute pathnames we need
         path combined with pathconvert -->
    <path id="foobar">
        <fileset dir="/home/gilreb/Downloads">
            <include name="*.zip"/>
        </fileset>
    </path>

    <pathconvert property="zipfiles" refid="foobar"/>

    <!-- iterate over the listentries, get access to
         the underlying fileobject and echo its properties -->
    <fl:for var="f" in="split('${zipfiles}', ':')">
        <echo>
      #{  format('filename %s, last modified %tD, size %s bytes', f.tofile.toabs,f.tofile.mtime,f.tofile.size)  }
     </echo>
    </fl:for>

</project>

output =

...  
   [echo]       filename /some/path/apache-ant-1.8.2-bin.zip, last modified 03/16/11, size 10920710 bytes
     [echo]      
     [echo]       filename /some/path/apache-ant-1.8.2-src.zip, last modified 03/16/11, size 8803388 bytes
     [echo]      
     [echo]       filename /some/path/apache-ant-antunit-1.1-bin.zip, last modified 04/17/11, size 70477 bytes
...

我认为这在任何核心 Ant 任务中都不可用。

您可以编写自己的自定义任务来执行此操作。

或者，您可以使用 Apply 任务来执行系统命令，例如 文件集中每个文件的 dir 。例如：

<apply executable="cmd" osfamily="windows">
<arg value="/c"/>
<arg value="dir"/>
<fileset dir=".">
  <include name="*.zip"/>
</fileset>
</apply>

按照下面的评论，您可以使用更新任务。

I don't think that is available in any of the core Ant tasks.

You could write your own custom task to do this.

Alternatively, you could use the Apply task to execute a system command like dir for each file in a fileset. For example:

<apply executable="cmd" osfamily="windows">
<arg value="/c"/>
<arg value="dir"/>
<fileset dir=".">
  <include name="*.zip"/>
</fileset>
</apply>

Following your comment below, you could check whether all your zip files were newer than some target file (which you could create before creation of the zips) using the Uptodate task.
