Netbeans刷新文件夹的插件

Netbeans中连刷新文件夹的功能都没有
还需要安装一个插件，插件名称
Scan On Demand


插件描述
Scan On Demand
With this module you can get more control over the scanning your IDE performs to keep internal information about your sources up to date. This module disables automatic scanning on start and after the main window gets focus. Instead you need to do it manually by invokig "refresh" action from various menus. Alternatively you can also create a configuration file and prevent changes in these files to trigger rescan.
