我从GitHub(https://github.com/vaadin-miki/vaadin-charts-video)下载了一个vaadin-charts-video示例项目的副本,以了解Vaadin图表应该如何实现.然而,该项目以及我发现的大多数可用演示代码/项目似乎都是使用Vaadin 7和先前的编码约定编写的.我正在使用Vaadin 8.0.5(和JDK8)...

运行Maven时出现这些错误:

例如,看到54号线https://github.com/vaadin-miki/vaadin-charts-video/blob/master/intro-video/src/main/java/org/vaadin/miki/charts/intro/IntroChartsUI的.java BeanItemContainer<BookPrice> container = new BeanItemContainer<>(BookPrice.class, prices);
