 I would like to understand why a BuildException is thrown when trying to parse
 a URL ?

 I disabled that exception throwing and in fact, I just use
 helper.parse(project, URL) with a URL and it works perfectly well.

 If there is no "good" reason or constraint about that exception, I would be
 pleased to see that part of code removed. Or simply disabled by a project
 property, why not. What do you think about it ? Is it possible to get it for
 release 1.6.3 (it will be a great help for me to release my build system) ?

 Thanks in advance for your help

<ProjectHelper2>
    public void parse(Project project, Object source, RootHandler handler)
            throws BuildException {

        AntXMLContext context = handler.context;

        File buildFile = null;
        URL  url = null;
        String buildFileName = null;

        if (source instanceof File) {
            buildFile = (File) source;
            buildFile = fu.normalize(buildFile.getAbsolutePath());
            context.setBuildFile(buildFile);
            buildFileName = buildFile.toString();
//         } else if (source instanceof InputStream ) {
        } else if (source instanceof URL) {
//             if (handler.getCurrentAntHandler() != elementHandler) {
//                 throw new BuildException(
//                     "Source " + source.getClass().getName()
//                     + " not supported by this plugin for "
//                     + " non task xml");
//             }
            url = (URL) source;
            buildFileName = url.toString();
//         } else if (source instanceof InputSource ) {
        } else {
            throw new BuildException("Source " + source.getClass().getName()
                                     + " not supported by this plugin");
        }
