maven父项目与子项目

maven父子项目的依赖，可以通过maven对项目进行分层。

父项目：

<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>hw.hlatform.secg</groupId>
	<artifactId>secg-parent</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>pom</packaging>//告诉父模块，什么包也不用生成
	<modules>//父页面所包含的子项目
		<module>../secg-core</module>
		<module>../secg-utils</module>
		<module>../secg-service</module>
		<module>../secg-pubilcinc</module>
		<module>../secg-webservice</module>
		<module>../secg-web</module>
		<module>../IHos-Api</module>
	</modules>

	<url>http://maven.apache.org</url>

	<properties>//编译的时候所用的编码
		<project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
	</properties>
