5在 war 中的 libs 搜索 Multimaps.class 可以看到如下 jar 中都存在对应的 com\google\common\collect\Multimaps.class

E:\huanyuWorkSpace\huanyu\trunk\target\shouwin-web-0.1-SNAPSHOT\WEB-INF\lib\google-collections-1.0.jar/com\google\common\collect\Multimaps.class将 pom 中的对应的 jar 的依赖关系分列出来，清晰可见对应的依赖关系

maven pom 依赖检查：
mvn 命令
- mvn dependency:analyze
- mvn dependency:tree
- mvn dependency:tree
- mvn dependency:tree -Dverbose 简单地用dependency:tree往往并不能查看到所有的传递依赖。不过如果你真的想要看所有的，必须得加一个-Dverbose参数，这时就必定是最全的了
- mvn dependency:tree -Dincludes 加上Dincludes或者Dexcludes，dependency:tree就会帮你过滤出来; 例如： Dincludes=org.springframework:spring-tx ；过滤串使用groupId:artifactId:version的方式进行过滤，可以不写全
使用示例：
mvn dependency:tree -Dverbose -Dincludes=com.google.guava:guava
