maven tomcat配置虚拟路径启动报错

Failed to execute goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.2:run (default-cli) on project zomore-headshop-web: Execution default-cli of goal org.apache.tomcat.maven:tomcat7-maven-plugin:2.2:run failed: addChild:  Child name '/images' is not unique

源码有问题吗

看了源码，把AbstractRunMojo里面的createStaticContext方法的host.addChild(staticContext);注释掉就可以了，请求大神讲解，还有没有更好的办法？
