利用Maven继承关系简化项目POM配置

昨天看到有人问依赖管理的问题，所以就想把自己在使用maven时的经验与大家进行分享。

 

1、首先建一个root/pom.xml

 主要作用就是配置一般项目都需要的基本信息。

如：编码，编译版本，生成eclipse项目时的编码，生成manifest描述，单元测试常用依赖，生成javadoc，生成source，eclipse:eclipse时自动关联source与javadoc，本地仓库配置等。

我定义的Final Name的格式是 ${project.artifactId}-${project.version}-r${svn.revision}-${maven.build.timestamp}，其中包含了svn的rev号与构建时的时间（我们用的是svn)

注意我用的maven-svn-revision-number-plugin 1.7目前不支持1.7格式的svn，官方插件目前已经升级到1.12了说是可以了，大家可以试试。

这种格式方便我们对产出的项目版本进行有效的跟踪(manifest中也有相关的信息)

文件名如：project1-core-1.0-SNAPSHOT-r82-20120503091343.jar
