Maven Multi-module Inheritance

 

所有用Maven管理的真实的项目都应该是分模块的，每个模块都对应着一个pom.xml.

 

1.聚合 POM与继承关系中的父POM的 packaging都是pom
2.聚合模块与继承关系中的父模块除了 POM之外都没有实际的内容。

注：在现有的实际项目中一个 POM既是聚合POM，又是父 POM，这么做主要是为了方便

In eclipse Run As -->maven build :  deploy -e
在parent pom.xml中
<modules>
    <module>../childModuleName</module>
    ......
  </modules>
在child pom.xml中
<parent>
    <groupId>...</groupId>
    <artifactId>...</artifactId>
    <version>0.0.1-SNAPSHOT</version>
    <relativePath>../parent/pom.xml</relativePath>
  </parent>
对parent  maven build 会build all modules.

maven build in eclipse:
Run As/Debug As--> maven clean, install, deploy ......  tomcat:run/tomcat7:run...

Struts2 scanning the actions in Jars:
<!--XXX-*-web-0.0.1-SNAPSHOT.jar-->   
 <constant name="struts.convention.action.includeJars" value=".*?/XXX-.+?-web.*?\.jar(!/)?"/>
并且XXX-*-web-0.0.1-SNAPSHOT.jar中必须包含标准的META-INF/MANIFEST.MF
