Generator.ClearAll 报错 Invalid AssetDatabase path: /XLua/Gen/ ，但是似乎并不影响最终结果

1. 删除 Assets/XLua/Gen/ 应该同时删除 Assets/XLua/Gen.meta
2. path 实际上为 C:/path/to/project/Assets/XLua/Gen/，而 AssetDatabase.DeleteAsset 要求传入 Assets/XLua/Gen/。原来的写法会报错。

Invalid AssetDatabase path: /XLua/Gen/. Use path relative to the project folder.

可以修改为

        static void clear(string path)
        {
            if (Directory.Exists(path))
            {
                Directory.Delete(path, true);
                string metaFilePath = path.TrimEnd('/') + ".meta";
                if (File.Exists(metaFilePath))
                {
                    File.Delete(metaFilePath);
                }
                if (path.StartsWith(Application.dataPath))
                {
                    path = "Assets" + path.Substring(Application.dataPath.Length);
                }
                AssetDatabase.DeleteAsset(path);

                AssetDatabase.Refresh();
            }
        }
