Need pattern matching in Ant for copying only parent folders

Question

Hello All,

I want to copy only the parent folders names from source and then create the folders with those names in a destination directory.

Ex: source - folder_1 - sub_1 - folder_2 - sub_2 - folder_3 - sub_3

destination - folder_1 - folder_2 - folder_3

Could you let me know the pattern matching for this requirement in ANT.

Regards, Satya

The way to do what you ask will depend on how you intend to use the driectory list once you have it, but it sounds like you need a dirset. Here's an example build file snippet:

<property name="src.dir" value="src" />
<dirset id="my.dirset" dir="${src.dir}" includes="*"/>
<echo message="${toString:my.dirset}" />

Specifying * for the includes attribute will pick up only directories at the top-level under ${src.dir}. Then, for example, the copy task can then be used to copy those (empty) directories somewhere:

<copy todir="${dest.dir}" >
    <dirset refid="my.dirset" />
</copy>
