Google maps GMapsFX显示空白地图

我收到两条错误消息：

ERROR com.lynden.gmapsfx.GoogleMapView - Error: User data directory [null (C:\Users\Admin\AppData\Roaming\application.Main\webview)] is already in use

及

我在Eclipse上使用JAVAFX11库，我已经编辑了我的运行配置以添加javafx.web模块。 我认为当我创建一个GoogleMapView对象时会出现问题，但我不知道如何解决！谢谢你给任何能帮助我的人的建议

这是我的控制器类：
