Ant: Rename sub-directories of the same name

Let's say I have a directory structure like this:

Using ant, I would like to rename all sub-directories under animals called details to now be named new. So the result would be this:

I've tried something like this:

    <move tofile="new">
        <path id="directories.to.rename">
            <dirset dir="animals">
                <include name="**/details"/>
            </dirset>
        </path>
    </move>

But get this error:

Cannot concatenate multiple files into a single file.

You can carry out the rename you describe by means of a mapper. For example:

<move todir="animals">
    <dirset dir="animals" includes="**/details" />
    <globmapper from="*/details" to="*/new"/>
</move>

(There's a similar example at the end of the move task docs.)

The error you saw arose because you've mixed the single-file mode of the move task (tofile) with multiple-file mode. There's no need to nest the dirset in a path as the move task accepts any file-based resource collection, including dirset.

Use Ant-Contrib's for task and propertyregex task.

<target name="test">
  <for param="detailsDir">
    <dirset dir="animals">
      <include name="**/details"/>
    </dirset>
    <sequential>
      <propertyregex property="output.dir" input="@{detailsDir}" regexp="(.*)/details" replace="\1" />
      <move file="@{detailsDir}" toFile="${output.dir}/new" />
    </sequential>
  </for>
</target>
