骨架 - 代码天地

maven骨架是一种快速生成模板项目的方法,这里记录创建、使用的过程

step1 从模板中骨架抽离

首先我们可以使用以下命令对一个模板项目进行骨架抽离工作。
所谓骨架抽离，其实就是将包名、groupId、artifactId、version参数化，抽离出一个用占位符号代替的工程。
mvn archetype:create-from-project

演示目录

该命令会将以上内容存入target.generated-sources.archetype目录中

产生抽离工程目录结构

这里有多个pom文件

第一个pom文件内容如下

<?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">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.jikee.template</groupId>
  <artifactId>template-boot-single-archetype</artifactId>
  <version>1.0-SNAPSHOT</version>
  <packaging>maven-archetype</packaging>

        <artifactId>archetype-packaging</artifactId>
        <version>3.0.1</version>
      </extension>
    </extensions>

    <pluginManagement>
      <plugins>
        <plugin>
          <artifactId>maven-archetype-plugin</artifactId>
          <version>3.0.1</version>
        </plugin>
      </plugins>
    </pluginManagement>
  </build>

这里注意下
<packaging>maven-archetype</packaging>
可以看到这个文件是用来做骨架的pom文件，而不是原文件

第二个pom文件内容如下

<?xml version="1.0" encoding="UTF-8"?>

                </plugin>
            </plugins>
        </pluginManagement>
    </build>

</project>

注意这里

   <groupId>${groupId}</groupId>
    <artifactId>${artifactId}</artifactId>
    <version>${version}</version>

可以看到一件被抽离了

step2 安装到本地或者发布到远程

在target.generated-sources.archetype目录中使用以下命令安装到本地和发布到远程
mvn archetype:install
mvn deploy
注意 mvn deploy 需要在target.generated-sources.archetype.pom.xml文件中指定发布源

<distributionManagement>
        <repository>
            <id>nexus-releases</id>
            <name>Nexus Release Repository</name>
            <url>http://frps:8081/nexus/content/repositories/releases/</url>
        </repository>
        <snapshotRepository>
            <id>nexus-snapshots</id>
            <name>Nexus Snapshot Repository</name>
            <url>http://frps:8081/nexus/content/repositories/snapshots/</url>
        </snapshotRepository>

    </distributionManagement>

step3 使用

在任意位置使用 mvn archetype:generate来弹出创建目录，选择刚刚建立的模板，输入提示的包名、groupId、artifactId、version信息即可创建

goodluck
