Question

我想将Vaadin图表添加到我的项目中，我添加了maven依赖项，安装许可证和vaadin clean，更新widgetset和编译。但是当我运行应用程序并打开localhost：8080时，在控制台中出错：

The widgetset in use does not seem to be built for the Vaadin
version in use. This might cause strange problems - a
recompile/deploy is strongly recommended.
Vaadin version: 8.0.0
Widgetset version: 8.0-SNAPSHOT

并在用户界面上显示以下消息：https://www.screencast.com/t/deDF6kVsvDdU

以下是我的pom.xml中的vaadin依赖：

    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-spring-boot-starter</artifactId>

    </dependency>
</dependencies>

            </configuration>
            <executions>
                <execution>
                    <goals>
                        <goal>update-theme</goal>
                        <goal>update-widgetset</goal>
                        <goal>compile</goal>
                        <goal>compile-theme</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

我该如何解决这个问题？

更新：以下是mvn vaadin:clean vaadin:compile的输出（运行此操作无法解决我的问题）：

[INFO] --- vaadin-maven-plugin:8.0.4:clean (default-cli) @ test ---
[WARNING] GWT plugin is configured to detect modules, but none were found.
[INFO]
[INFO] --- vaadin-maven-plugin:8.0.4:compile (default-cli) @ test ---
[WARNING] GWT plugin is configured to detect modules, but none were found.
[INFO] Using com.vaadin:vaadin-client version 8.0.0
[INFO] Using com.vaadin:vaadin-client-compiler version 8.0.0
[INFO] ---------------------------------------------------------------------
[INFO] BUILD SUCCESS

我还尝试向VaadinUI类添加注释@Widgetset("AppWidgetset")并重新编译，这次我在UI上出错：

Failed to load the widgetset: ./VAADIN/widgetsets/AppWidgetset/AppWidgetset.nocache.js?

所以，我在VaadinUi类附近添加了WidgetSet.gwt.xml：

<?xml version="1.0" encoding="UTF-8"?>
<module>
    <inherits name="com.vaadin.DefaultWidgetSet" />
    <inherits name="com.vaadin.addon.charts.Widgetset" />
</module>

重新编译所有内容，但仍然可以

 Failed to load the widgetset: ./VAADIN/widgetsets/AppWidgetset/AppWidgetset.nocache.js?

Answer 1

添加vaadin client dep

<dependency>
    <groupId>com.vaadin</groupId>
    <artifactId>vaadin-client</artifactId>
    <scope>provided</scope>
</dependency>

Answer 2

My POM as below and it worked. Build command as normal: mvn package. Only need to compile widget once so remove plugin when you build your app to reduce compile time. VAADIN folder to compile is at: \src\main\webapp\VAADIN

<!-- Only support to compile Vaadin widgetsets -->
   .......
    <dependency>
        <groupId>com.vaadin</groupId>
        <artifactId>vaadin-client</artifactId>
        <scope>provided</scope>
        <version>8.2.0</version>
    </dependency>
       .....
       <plugin>
            <groupId>com.vaadin</groupId>
            <artifactId>vaadin-maven-plugin</artifactId>
            <version>8.2.0</version>
            <executions>
                <execution>
                    <goals>
                        <goal>update-theme</goal>
                        <goal>update-widgetset</goal>
                        <goal>compile</goal>
                        <goal>compile-theme</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>

正在使用的widget集似乎不是为正在使用的Vaadin版本构建的
