Ant脚本中的资源计数

Question

我只需要知道如何修改下面的代码，以便蚂蚁确定我的文本文件中的行数（请注意这里的所有文本文件将具有相同的行数，但该数字不固定）并自动执行它们基于循环。

＆＃13;

＆＃13;

<project name="ant-read-n-files" default="run" basedir=".">
  
  <!-- Load the ant contrib lib -->
  <taskdef resource="net/sf/antcontrib/antlib.xml">
    <classpath>
      <pathelement location="${basedir}/lib/ant-contrib.jar"/>
    </classpath>
  </taskdef>
  
  <target name="read">
    <!-- file a -->
    <loadfile property="textFileA" srcfile="${basedir}/files/aaa.txt">
      <filterchain>
        <headfilter lines="1" skip="${linenum}"/>
      </filterchain>
    </loadfile>
    <for param="line" list="${textFileA}" delimiter="${line.separator}">
      <sequential>
        <property name="textFileAValue" value="@{line}"/>
      </sequential>
    </for>
    <!-- file b -->
    <loadfile property="textFileB" srcfile="${basedir}/files/bbb.txt">
      <filterchain>
        <headfilter lines="1" skip="${linenum}"/>
      </filterchain>
    </loadfile>
    <for param="line" list="${textFileB}" delimiter="${line.separator}">
      <sequential>
        <property name="textFileBValue" value="@{line}"/>
      </sequential>
    </for>
    <!-- file c -->
    <loadfile property="textFileC" srcfile="${basedir}/files/ccc.txt">
      <filterchain>
        <headfilter lines="1" skip="${linenum}"/>
      </filterchain>
    </loadfile>
    <for param="line" list="${textFileC}" delimiter="${line.separator}">
      <sequential>
        <property name="textFileCValue" value="@{line}"/>
      </sequential>
    </for>
 
    <!-- Print them all -->
    <echo message="${textFileAValue}"/>
    <echo message="${textFileBValue}"/>
    <echo message="${textFileCValue}"/>
  </target>
 
  <target name="run">
    <foreach param="linenum" list="0,1,2" target="read"/>
  </target>
</project>

＆＃13;

＆＃13;

在这里你看到list =＆＃34; 0,1,2＆＃34;意味着循环将验证每个文本文件的前三行，但我希望它是动态的，具体取决于文件所具有的行数。 非常感谢任何帮助。

谢谢， 阿什利
