maven项目继承及依赖

最近一个简单的搜索项目利用maven 特性构建

项目目录结构：

lifeix-search-api
├── lifeix-search-api-bean
│   ├── pom.xml
│   └── src
│       ├── main
│       └── test
├── lifeix-search-api-client
│   ├── pom.xml
│   └── src
│       ├── main
│       └── test
├── lifeix-search-api-server
│   ├── pom.xml
│   └── src
│       ├── main
│       └── test
└── pom.xml

\1. lifeix-search-api 为项目根目录，有一个pom.xml 文件，为lifeix-search-api-bean，lifeix-search-api-client，lifeix-search-api-server 三个项目的父pom文件

4.0.0 com.lifeix lifeix-search-api 0.1.0-SNAPSHOT pom lifeix-search-api lifeix-search-api-bean lifeix-search-api-client lifeix-search-api-server UTF-8svn://${svnURL} 1.17.1 ... ...各种依赖

lifeix-search-api 在myeclipse 下表现如图：

将父pom.xml 文件deploy 到maven 私服中. 以便子项目可独立依赖。

2.进入lifeix-search-api-bean 项目中。其pom.xml 文件如下。

<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/maven-v4_0_0.xsd">

<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>lifeix-search-api</artifactId>
<groupId>com.lifeix</groupId>
<version>0.1.0-SNAPSHOT</version>
</parent>

<groupId>com.lifeix</groupId>
<artifactId>lifeix-search-api-bean</artifactId>
</project>

其它所有属性依赖父pom文件

由于lifeix-search-api-client lifeix-search-api-server
都依赖lifeix-search-api-bean 项目，为让这两个项目可独立打包
需将lifeix-search-api-bean deploy 到maven 私服 mvn package source:jar
javadoc:jar deploy

3.进入lifeix-search-api-client 项目中.其pom.xml 文件如下:

<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>lifeix-search-api</artifactId>
<groupId>com.lifeix</groupId>
<version>0.1.0-SNAPSHOT</version>
</parent>
<groupId>com.lifeix</groupId>
<artifactId>lifeix-search-api-client</artifactId>
<version>0.1.0-SNAPSHOT</version>

<dependencies>
<!-- oauth-client -->
<dependency>
<groupId>com.sun.jersey.contribs.jersey-oauth</groupId>
<artifactId>oauth-client</artifactId>
<version>1.17.1</version>
</dependency>

<!-- oauth-signature -->
<dependency>
<groupId>com.sun.jersey.contribs.jersey-oauth</groupId>
<artifactId>oauth-signature</artifactId>
<version>1.17.1</version>
</dependency>

<!--  依赖 bean jar  -->
<dependency>
<groupId>com.lifeix</groupId>
<artifactId>lifeix-search-api-bean</artifactId>
<version>0.1.0-SNAPSHOT</version>
</dependency>

</dependencies>

</project>

可以看到此pom.xml 文件只需配置很少依赖

4.进入lifeix-search-api-server 项目中.其pom.xml 文件如下:

<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/maven-v4_0_0.xsd">
<modelVersion>4.0.0</modelVersion>
<parent>
<artifactId>lifeix-search-api</artifactId>
<groupId>com.lifeix</groupId>
<version>0.1.0-SNAPSHOT</version>
</parent>
<groupId>com.lifeix</groupId>
<artifactId>lifeix-search-api-server</artifactId>
<packaging>war</packaging>
<properties>
<jackson.version>1.9.12</jackson.version>
<mysql.connector.version>5.1.24</mysql.connector.version>
</properties>

<dependencies>
<!-- bean -->
<dependency>
<groupId>com.lifeix</groupId>
<artifactId>lifeix-search-api-bean</artifactId>
<version>0.1.0-SNAPSHOT</version>
</dependency>

<!-- other dependency -->
<dependency>
... others 
</dependency>

</dependencies>

</project>

由于lifeix-search-api-server 为web 项目，则packaging设置为war 打包为war
包

OK. 我们可以在lifeix-search-api 目录下执行:

 mvn package -DskipTests

也可以到各自项目目录下执行 maven 命令.
