添加googlemaps Vaadin库后，vaadin不编译Widgetset

Question

今天，我尝试将googlemaps图书馆添加到我的vaadin项目中。我将所需的依赖项添加到我的pom.xml中，但是在我添加了库之后，maven不想重新编译我的widgetset，因为这个错误：

    Tracing compile failure path for type 'com.vaadin.tapio.googlemaps.client.GoogleMapConnector'
[INFO]       [ERROR] Errors in 'jar:file:/C:/Users/kolbm/.m2/repository/com/vaadin/tapio/googlemaps/2.0.0/googlemaps-2.0.0.jar!/com/vaadin/tapio/googlemaps/client/GoogleMapConnector.java'

希望有人知道该怎么做，因为我在网上什么都没发现.

您使用的是vaadin 7，但是googlemaps插件的2.0.0版本是针对vaadin 8的。
