<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.tian</groupId>
  <artifactId>Web-Maven</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>war</packaging>


</project>
