FTB source launcher error

[crizip]

Hi all ! i have bug for test ftb source on eclipse :

Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException: 0
at net.ftb.mclauncher.MinecraftLauncherNew.main(MinecraftLauncherNew.java:167)

ligne 167 :

 public static void main (String[] args) {
        String basepath = args[0], animationname = args[1], forgename = args[2], username = args[3], password = args[4], modPackName = args[5], modPackImageName = args[6];
        Settings.getSettings().save(); //Call so that the settings file is loaded from the correct location.  Would be wrong on OS X and *nix if called after user.home is reset

        basepath = new File(basepath).getAbsoluteFile().toString().replaceAll("[/\\\\]$", "");
        ;

        try {
            System.out.println("Loading jars...");
            String[] jarFiles = new String[] { "minecraft.jar", "lwjgl.jar", "lwjgl_util.jar", "jinput.jar" };
            ArrayList<File> classPathFiles = new ArrayList<File>();
            File tempDir = new File(new File(basepath).getParentFile(), "instMods/");
            if (tempDir.isDirectory()) {
                for (String name : tempDir.list()) {
                    if (!name.equalsIgnoreCase(forgename)) {
                        if (name.toLowerCase().endsWith(".zip") || name.toLowerCase().endsWith(".jar")) {
                            classPathFiles.add(new File(tempDir, name));
                        }
