[Maven]自定义Archetypes

Archetypes就相当于脚手架，如果在平常项目中，有个基础的模版，你就可以直接基于模版构建项目，

1. 新建一个maven项目，定义项目pom.xml

<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">
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.ppdai.cbd.ddp</groupId>
    <artifactId>flinkCustomArchitype</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>maven-archetype</packaging>

    <build>
        <extensions>
            <extension>
                <groupId>org.apache.maven.archetype</groupId>
                <artifactId>archetype-packaging</artifactId>
                <version>3.1.1</version>
            </extension>
        </extensions>
    </build>
</project>

2.创建 archetype描述文件，文件所在目录  （项目根目录）flinkCustomArchitype/src/main/resources/META-INF/maven

<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"
        xmlns="http://maven.apache.org/plugins/maven-archetype-plugin/archetype-descriptor/1.0.0"
        xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
        name="flinkCustomArchitype">
    <fileSets>
        <fileSet filtered="true" packaged="true">
            <directory>src/main/java</directory>
        </fileSet>
    </fileSets>
</archetype-descriptor>

3. 目录结构 

archetype
|-- pom.xml
`-- src
    `-- main
        `-- resources
            |-- META-INF
            |   `-- maven
            |       `--archetype-metadata.xml
            `-- archetype-resources
                |-- pom.xml  （prototype pom.xml）

                `-- src
                    |-- main
                    |   `-- java
                    |       `-- App.java
                    `-- test
                        `-- java
                            `-- AppTest.java

4. 创建 prototype pom.xml

<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">
    <modelVersion>4.0.0</modelVersion>
 
    <groupId>${groupId}</groupId>
    <artifactId>${artifactId}</artifactId>
    <version>${version}</version>
    <packaging>jar</packaging>
 
    <name>${artifactId}</name>
    <url>http://www.myorganization.org</url>
 
    <dependencies>
        <dependency>
                <groupId>junit</groupId>
                <artifactId>junit</artifactId>
                 <version>4.12</version>
                <scope>test</scope>
        </dependency>
    </dependencies>
</project>

5. mvn install  本地安装

6. cd 一个空目录，执行

mvn archetype:generate                                  
  -DarchetypeGroupId=<archetype-groupId>                
  -DarchetypeArtifactId=<archetype-artifactId>          
  -DarchetypeVersion=<archetype-version>                
  -DgroupId=<my.groupid>                                
  -DartifactId=<my-artifactId>
