java - Vaadin 小部件集编译失败

Question

我使用 vaadin-maven-plugin:8.1.2 因为我想要拥有与默认不同的小部件集。 当我编译 widgetset(通过 Vaadin eclipse 插件)时，我得到:

首先我想问一下如何强制插件使用这个:org.vaadin.sliderpanel.WidgetSet？它总是尝试编译 com.vaadin:vaadin-client version AppWidgetset.gwt.xml 是在 target/generated-resources/gwt 中自动创建的，生成的继承是我真正想要的，但不知何故插件找不到它。

这是我的 web.xml 文件:

</web-app>

从 pom.xml 构建部分

<build>
    <pluginManagement>
        <plugins>
            <plugin>
                <groupId>com.vaadin</groupId>

我花了几个小时来处理它，当时只是将生成的 AppWidgetset.gwt.xml 文件放入 src/main/resources。
