relative filename build.xml

            var base = myProject.getProperty("target");
            relativeFileName = relativeFileName.replace(base+"\\","");
            relativeFileName = relativeFileName.replace("\\","/");
            myProject.setProperty("relativeFileName", relativeFileName);

</project>

This example shows

• how to loop over files
• how to make the filename relative
• how to put this information into a file

For this to be able to run you'll need an additional jar file: ant-contrib.jar
