Creator2.3 对接Sdkbox报错没有sdkbox.PluginAdMob.setListener

Creator 2.x
#1

求助，Cocos Creator 2.3.0

根据教程对接Sdkbox https://docs.cocos.com/creator/manual/zh/sdk/sdkbox.html

项目是TypeScript的，打包Android工程，勾选SDKBox构建后，

sdkbox.PluginAdMob.setListener({
  adViewDidReceiveAd: function(name) {
  	self.showInfo('adViewDidReceiveAd name=' + name);
  },
  adViewDidFailToReceiveAdWithError: function(name, msg) {
  	self.showInfo('adViewDidFailToReceiveAdWithError name=' + name + ' msg=' + msg);
  },
  adViewWillPresentScreen: function(name) {
  	self.showInfo('adViewWillPresentScreen name=' + name);
  },
  adViewDidDismissScreen: function(name) {
  	self.showInfo('adViewDidDismissScreen name=' + name);
  },
  adViewWillDismissScreen: function(name) {
  	self.showInfo('adViewWillDismissScreen=' + name);
  },
  adViewWillLeaveApplication: function(name) {
  	self.showInfo('adViewWillLeaveApplication=' + name);
  }
});

运行报错，

E/jswrapper: ERROR: Uncaught TypeError: Cannot read property 'setListener' of undefined, location: src/cocos2d-jsb.js:0:0

是不是没有sdkbox.PluginAdMob 了。

求助，谢谢
