是Morfic是对的，我通过在pom.xml中添加以下内容来解决问题
<plugin>
<groupId>com.vaadin</groupId>
<artifactId>vaadin-maven-plugin</artifactId>
<version>${vaadin.plugin.version}</version>
<executions>
<execution>
<goals>
<goal>update-theme</goal>
<goal>update-widgetset</goal>
<goal>compile</goal>
<!-- Comment out compile-theme goal to use on-the-fly theme compilation -->
<goal>compile-theme</goal>
</goals>
</execution>
</executions>
</plugin>
