Try something like this (
import java.io.File;
import java.io.IOException;
import java.util.Enumeration;
import java.util.Vector;
import org.apache.tools.ant.BuildException;
import org.apache.tools.ant.DirectoryScanner;
import org.apache.tools.ant.Task;
import org.apache.tools.ant.Project;
import org.apache.tools.ant.types.FileSet;
public class AntFileSetTest extends Task{
private Vector filesets = new Vector();
public void addFileset(FileSet fileset) {
filesets.add(fileset);
}
public void execute(){
log("executing Xindice Ant Task");
int fileCount = 0;
int successCount = 0;
Enumeration enum = filesets.elements();
while(enum.hasMoreElements()){
FileSet fileset = (FileSet) enum.nextElement();
DirectoryScanner ds = fileset.getDirectoryScanner(getProject());
String[] files = ds.getIncludedFiles();
for(int i=0; i<files.length; i++) {
fileCount++;
File f = new File(fileset.getDir( getProject()
),files[i]);
if (process(f)){
successCount++;
}
}
}
System.out.println("task working properly");
}
protected boolean process(File file){
//work done here on a per file basis
System.out.println("file processed");
return true;
}
}
With ant snippet ( remember to use taskdef )
<test>
<fileset dir="somedir">
<include name="**/*.*"/>
</fileset>
</test>
The output would be a the 'file processed' message displaying per
included file.
