Search for folders and access them
Hello Users,
I'm working with a folders hierarchy and I don't know the names of the
subfolders. Is it possible with ANT to go into every subfolder which
exist or I must use an external application?
I want to check every folder to see if contains a certain file and do
things depending the file contained into the folder. The actions I know
how to do it with ANT, but not the way to search into all subfolders.
Can anyone help me?
Thank you very much.
Best regards,

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>

Thank you very much Jan,
In this way.... how can I process this fileset to get the path to move to the folder and then do something? Is this possible?
Sorry, I'm new with ANT and I've looking for the help about fileset but not understand it well.
Thank you very much.

Ant does "not go into" a folder.
It scans them.
You could define a <fileset> which returns only the paths to these files:
<fileset dir="." includes="**/certain.file"/>
Here the wildcard "**" is interesting: every subdirectory including recursive.
If you only want the directories directly under "." choose the "*" wildcard.
