我更改了pom.xml文件＆＃39; s vaadin版本号和vaadin插件版本号
后构建失败<vaadin.version>7.4.5</vaadin.version>
<vaadin.plugin.version>7.4.5</vaadin.plugin.version>
然后我尝试清理并重建项目，但构建失败显示出：

有关此确切问题，请参阅此forum thread。该错误源自您在类路径中具有不同版本的org.ow2.asm:asm。你必须找到罪魁祸首（maven中的依赖关系），然后在之前放入适当的dep 。 E.g：
<dependency>
<groupId>org.ow2.asm</groupId>
<artifactId>asm</artifactId>
<version>5.0.3</version>
<scope>provided</scope>
</dependency>
