Back from holiday I am doing my emails ...
... and have a solution for you :-)


I used the <script> task for iterating over the selected files of a=20
fileset, instatiate a java.io.File object and gets that filesize using
its length() method.
As a result I stored the value as ant property (with common prefix).

A quick shot but works for me.=20
Here is the build file:

<?xml version=3D"1.0" encoding=3D"ISO-8859-1"?>
<project name=3D"test" basedir=3D"." default=3D"main">
    <target name=3D"main">
        <!-- for what files the size is required? -->
        <fileset id=3D"fs" dir=3D"test"/>

        <!-- use java.io.File in script task for getting that size -->
        <script language=3D"javascript"> <![CDATA[

            // iterate over the files selected by the fileset defined =
above
            // code adapted from copy task implementation

            // Get the DirectoryScanner
            // project is an object defined by script task
            ds =3D fs.getDirectoryScanner(project);

            // Get the source files (array)
            srcFiles =3D ds.getIncludedFiles();

            // iterate over that array
            for (i=3D0; i<srcFiles.length; i++) {
                filename =3D srcFiles[i];
                file =3D new java.io.File(fs.getDir(project), =
filename);
                size =3D file.length();

                // store the size an a property
                // prefix.filename=3Dsize
                project.setProperty("filesize."+filename,size);
            }
        ]]> </script>

        <!-- prints the sizes -->
        <echoproperties prefix=3D"filesize"/>

    </target>
</project>
