1，創建用於創建archetype的project

mvn archetype:generate -DgroupId=com.ultrapower.archetypes -DartifactId=ultra-template-archetype -DarchetypeArtifactId=maven-archetype-quickstart -Dversion=1.0 -DinteractiveMode=false
 

其中關於添加相關的依賴等這裏忽略

2，打開cmd,在project的根目錄執行以下命令

mvn archetype:create-from-project

通過該命令，會在target目錄下面生成generated-sources/archetype目錄，這個就是生成的 archetype。 (同時，generated-sources\archetype\src\main\resources\META-INF\maven下的文件archetype-metadata.xml可能需要調整)

先來看看archetype下的pom.xml都包含些什麽內容

<?xml version="1.0" encoding="UTF-8"?>
<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/xsd/maven-4.0.0.xsd">

我們再打開archetype-metadata.xml文件看看裏面的內容，並做可能的必要修改

<?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="ultra-template-archetype"
    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>**/*.java</include>
        <include>**/*.xml</include>
      </includes>
    </fileSet>
    <fileSet filtered="true" encoding="UTF-8">
      <directory>src/main/resources</directory>
      <includes>
        <include>**/*.xml</include>
        <include>**/*.html</include>
      </includes>
    </fileSet>
    <fileSet encoding="UTF-8">
      <directory>src/main/resources</directory>
      <includes>
        <include>**/*.yml</include>
      </includes>
    </fileSet>
    <fileSet filtered="true" packaged="true" encoding="UTF-8">

      <includes>
        <include>**/*.java</include>
      </includes>
    </fileSet>
    <fileSet encoding="UTF-8">
      <directory>lib</directory>
      <includes>
        <include>**/*.jar</include>
      </includes>
    </fileSet>
    <fileSet encoding="UTF-8">
      <directory>boot</directory>
      <includes>
        <include>**/*.bat</include>
        <include>**/*.sh</include>
      </includes>
    </fileSet>
    <fileSet encoding="UTF-8">
      <directory>.settings</directory>
      <includes>
        <include>**/*.prefs</include>
      </includes>
    </fileSet>
    <fileSet filtered="true" encoding="UTF-8">
      <directory></directory>
      <includes>
        <include>.classpath</include>
        <include>.project</include>
      </includes>
    </fileSet>
  </fileSets>
</archetype-descriptor>
 

將最後的兩項去掉即可滿足需要了

<fileSet encoding="UTF-8">
      <directory>.settings</directory>
      <includes>
        <include>**/*.prefs</include>
      </includes>
    </fileSet>
    <fileSet filtered="true" encoding="UTF-8">
      <directory></directory>
      <includes>
        <include>.classpath</include>
        <include>.project</include>
      </includes>
    </fileSet>

在此簡單說下幾個屬性的含義(完整的說明參考官網archetype-metadata.xml詳解)
1）filtered ：被選擇的文件是否當做 Velocity 模板來使用(如果是true則可以使用Velocity的表達式，例如用於動態設置包名等)
2）packaged：被拷貝或生成(通過Velocity生成)的文件是否在package屬性預先設置的目錄結構下進行存放
3）encoding：設置文件的字符編碼

3，cd進入generated-sourced/archetype目錄並執行以下命令

mvn install

通過以上操作便會將自定義的archetype安裝到maven倉庫中，同時會在倉庫根目錄下的archetype-catalog.xml文件中添加自定義archetype的信息(沒有會自動創建該文件)

4，使用自定義的archetype創建project

mvn archetype:generate  -DarchetypeGroupId=com.ultrapower.archetypes  -DarchetypeArtifactId=ultra-template-archetype-archetype  -DarchetypeVersion=1.0 -DgroupId=com.ultrapower.ioss -DartifactId=ultra-template-archetype-test -X

至此，一個新的project便生成

重要：對於某些java和文本文件裏面的配置可能需要動態修改，所以需要手動的調整archetype下的文件，在此不再贅述
