今天我尝试添加 a googlemaps library到我的 vaadin 项目。 我将所需的依赖项添加到了我的 pom.xml 中，但是在添加库后，maven 不想重新编译我的小部件集，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，因为我在互联网上什么也没找到......
最佳答案
您使用的是 vaadin 7，但 2.0.0 版 googlemaps 插件针对的是 vaadin 8。 尝试使用 1.3.4 版 googlemaps 插件
关于java - 添加 googlemaps vaadin 库后 Vaadin 不编译 Widgetset，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/43920172/
