用eclipse编写自定义archetype

archetype：翻译成原型，其实就是我们所谓的脚手架。

maven已经给我们提供了很多archetype，但很多时候我们还需要自己手工去做属于自己的个性化archetype。

 

1、做一个maven工程（model-project）（包括了工具类，配置文件，等），我们的目标是通过自定义的archetype可以生成这个工程的样子。

2、右键工程model-project  run as 运行命令：archetype:create-from-project，该命令会生成/target/generated-sources/archetype代码。

3、新建一个普通java工程template,右键configure--->conver to maven 填写上maven坐标，删除src目录，备份pom.xml。

4、把第2步生成的/target/generated-sources/archetype下面的代码都copy到template工程中，覆盖原有代码，修改pom.xml中的坐标为备份中的坐标，同时必面把version中的SNAPSHOT去掉，保证不是快照才能在后面看到该archetype。

5、install template工程。

6、这里新建工程时，在default local 中就能选中刚才我们自己定义的archetype了。

 

注意：有时需要修改/src/main/resources/META-INF/maven/archetype-metadata.xml该文件

filtered：是否过滤，比如用用户输入的坐标，包名来替换类中的包名，坐标。

packaged：是否按包输出，比如src/main/java会级联生成三个目录。

文件一般结构为：

<?xml version="1.0" encoding="UTF-8"?>
<archetype-descriptor xsi:schemaLocation="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-descriptor/1.0.0 http://maven.apache.org/xsd/archetype-descriptor-1.0.0.xsd" name="hello-api"
    xmlns="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-descriptor/1.0.0"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
  <fileSets>
    <fileSet filtered="true" packaged="true" encoding="UTF-8">
      <directory>src/main/java</directory>
      <includes>
        <include>**/*.*</include>
      </includes>
    </fileSet>
    <fileSet filtered="true" packaged="flase" encoding="UTF-8">
      <directory>src/main/php</directory>
      <includes>
        <include>**/*.*</include>
      </includes>
    </fileSet>
 </fileSets>   
</archetype-descriptor>

 

很容易看明白，但有一种特殊情况是parent工程结构如下：

<modules>
		<module dir="api" name="service-api">
			<fileSets>
				<fileSet filtered="true" encoding="UTF-8" packaged="true">
