Question

我正在尝试使用正则表达式删除一组目录，但根本没有太多运气，任何人都可以看看目标：

    <delete failonerror="true" includeemptydirs="true">
        <dirset dir="C:\Users\martin\Desktop\testing" includes="*">
            <containsregexp expression="[0-9]*-0" />
        </dirset>
     </delete>

它只是不会删除文件，我希望它与文件夹[0-9] * - 0匹配，如果匹配，则删除它

删除任务将删除单个目录，但不删除dirset中的目录。

我有以下目录结构：

C:\dev\debug_investigations\purge_deployment\test\012345-0
C:\dev\debug_investigations\purge_deployment\test\012345-1
C:\dev\debug_investigations\purge_deployment\test\987565-0
C:\dev\debug_investigations\purge_deployment\test\012345-0\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\012345-0\subdir1
C:\dev\debug_investigations\purge_deployment\test\012345-0\subdir2
C:\dev\debug_investigations\purge_deployment\test\012345-0\subdir1\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\012345-0\subdir2\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\012345-1\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir1
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir2
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir1\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir2\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\987565-0\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\987565-0\subdir1
C:\dev\debug_investigations\purge_deployment\test\987565-0\subdir2
C:\dev\debug_investigations\purge_deployment\test\987565-0\subdir1\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\987565-0\subdir2\sometext.txt

我创建了这个蚂蚁目标（蚂蚁1.8.2）

   <target name="regexptest">
      <fileset dir="C:\dev\debug_investigations\purge_deployment\test\" includes="**/**" id="regexp.todelete">
          <filename regex="[0-9]*-0" />
      </fileset>
      <!-- Which files are selected? -->
      <pathconvert pathsep="${line.separator}" property="prop.regexp.test" refid="regexp.todelete" />
      <echo message="Will delete:" />
      <echo message="${prop.regexp.test}" />
      <delete failonerror="true" includeemptydirs="true" verbose="true">
        <fileset refid="regexp.todelete" />
     </delete>
   </target>

任务运行后的目录结构：

C:\dev\debug_investigations\purge_deployment\test\012345-1
C:\dev\debug_investigations\purge_deployment\test\012345-1\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir1
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir2
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir1\sometext.txt
C:\dev\debug_investigations\purge_deployment\test\012345-1\subdir2\sometext.txt

它比生产需要的更冗长，但我希望这有助于未来的regex目录删除！
