maven parent pom

parent pom：全局定义项目模型，子pom继承父pom的配置

主要配置：

定义项目基本信息:比如license

<licenses>

<license>

<name>The Apache Software License, Version 2.0</name>

<url>http://www.apache.org/licenses/LICENSE-2.0.txt</url>

<distribution>repo</distribution>

</license>

</licenses>

定义公司统一仓库位置：比如jardeploy位置

<!-- 发布位置配置 -->

<distributionManagement>

<repository>

<id>nexus-releases</id>

<name>Internal Release Repository</name>

<url>http://nexus.xxx.com/content/repositories/releases/</url>

</repository>

<snapshotRepository>

<id>nexus-snapshots</id>

<name>Internal Snapshot Repository</name>

<url>http://nexus.xxx.com/content/repositories/snapshots/</url>

</snapshotRepository>

</distributionManagement>

定义全局插件：比如built方式

<plugins>

<plugin>

<inherited>true</inherited>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-compiler-plugin</artifactId>

<configuration>

<source>1.6</source>

<target>1.6</target>

<optimize>true</optimize>

<debug>true</debug>

</configuration>

</plugin>

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-resources-plugin</artifactId>

<configuration>

<encoding>UTF-8</encoding>

</configuration>

</plugin>

<!-- 发布源代码jar -->

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-source-plugin</artifactId>

<version>2.1.2</version>

<executions>

<execution>

<id>attach-sources</id>

<phase>deploy</phase>

</execution>

</executions>

</plugin>

<!-- 发布javadoc -->

<plugin>

<groupId>org.apache.maven.plugins</groupId>

<artifactId>maven-javadoc-plugin</artifactId>

<version>2.8.1</version>

<executions>

<execution>

<id>attach-javadocs</id>

<goals>

<goal>jar</goal>

</goals>

</execution>

</executions>

</plugin>

</plugins>

</build>

统一管理jar版本：子项目在引入jar时不需要加入version 和scope属性：例如

<!--管理jar包版本-->

<dependencyManagement>

<dependencies>

<dependency>

<groupId>com.peaceful</groupId>

<artifactId>nuggets-peaceful-utils</artifactId>

<version>1.0-SNAPSHOT</version>

</dependency>

</dependencies>

</dependencyManagement>

定义公司统一jar包依赖：这样所有通过配置parent的项目都可以把下面jar依赖到自己项目里，例如

<dependencies>

<!--  JUNIT DEPENDENCY FOR TESTING -->

<dependency>

<groupId>junit</groupId>

<artifactId>junit</artifactId>

<version>${junit.version}</version>

<scope>test</scope>

</dependency>

</dependencies>

总结parent pom主要是用来全局描述项目模型
