我想创建一个for循环来迭代文件的行。 我做了:
<loadfile property="download.file" srcfile="download_list.txt"/>
<target name="criarArvore">
<mkdir dir="${download.dir}"/>
<mkdir dir="${domain.dir}"/>
</target>
<target name="download" depends="criarArvore">
<for param="line" list="${download.file}" delimiter="${line.separator}">
<sequential>
<echo>@{line}</echo>
</sequential>
</for>
</target>
但在<for>
intellij警告我:&#39;无法解析符号&#34;对于&#34;&#39;。
当我运行脚本时,我收到:
c:\xxx\build.xml:22: Problem: failed to create task or type for

<for>
task来自第三方Ant-Contrib library。
