In Ant you usually have ONE action which processes a bunch of resources.
E.g. instead of iterating over a fileset and copying each individual file you
have
<copy todir=""><fileset.../></copy>
There are many tasks which support filesets, paths or resource collections.
A resource collection (as the most abstract type of these resources) returns
resources
after a check by a "selector".
Example: <fileset dir="."><filename regex="foo.*"/></fileset>
The file scanner scans the base directory recursively. Each file is passed to
the <filename> selector
which "selects" the file if the name matches the given regular expression.
So selecting certain files is easy.
Selecting directories which contains a special "marker file" is more tricky...
<!-- The dirset which contains only marked directories -->
<dirset id="dirset" dir="${workingdir}">
<present targetdir="${workingdir}">
<mapper type="glob" from="*" to="*/${markerfile}" />
</present>
</dirset>
or
<!-- The dirset which contains only marked directories -->
<dirset id="dirset" dir="${workingdir}">
<scriptselector language="javascript">
if (file.isDirectory()) {
markerName = project.getProperty("markerfile");
markerFile = new java.io.File(file, markerName);
self.setSelected( markerFile.exists() );
}
</scriptselector>
</dirset>
