我是spring的天真用户。我刚刚开始学习它。我想通过理解例子来学习spring。所以我尝试从链接https://github.com/SpringSource/spring-petclinic安装 spring 的 petclicnic 示例应用程序。当我尝试运行 mvn install 命令时，出现以下错误 java.lang.NoClassDefFoundError: org/springframework/beans/factory/NoUniqueBeanDe finitionException。我尝试使用https://jira.springsource.org/browse/SPR-10218中提供的信息来解决它。我添加了所有依赖项。现在我收到以下错误。请帮忙
