Vaadin的widgetset编译故障

Question

Im使用vaadin-maven-plugin：8.1.2因为我想有不同的widgetset比默认的。 当我编译视窗元件（由Vaadin Eclipse插件）我得到这样的：

[INFO] No widgetsets found - generating AppWidgetset if necessary.

首先我想问我怎么能强迫插件来用这个的：org.vaadin.sliderpanel.WidgetSet？它总是试图编译com.vaadin:vaadin-client version AppWidgetset.gwt.xml是在target/generated-resources/gwt中自动创建的，具有我实际需要的生成的继承，但不知何故插件无法找到它。

这里是我的web.xml文件：

构建部分从pom.xml的

<build> 
    <pluginManagement> 
     <plugins> 
      <plugin> 
       <groupId>com.vaadin</groupId> 
       <artifactId>vaadin-maven-plugin</artifactId> 
       <version>${vaadin.plugin.version}</version>

        <style>OBF</style>

       </configuration>

我花就像对付它几个小时，当它正要推杆产生AppWidgetset。 gwt.xml文件到src/main/resources。
