构建系统maven

1 前言

说真的，我是真的不想看构建了，因为真的太多了。又多又乱。Maven、Gradle、Make、CMake、Meson、Ninja，Android BP。。。感觉学不完，根本学不完。。。

但是没办法最近又要用一下Maven，所以咬着牙再简单整理一下。

安装：

sudo apt update
sudo apt install maven
mvn -v

功能：

功能	说明
📦 依赖管理	自动下载并管理第三方 JAR 包
🔨 项目构建	编译 Java、打包成 JAR/WAR 等
📁 项目结构标准化	统一目录结构，便于协作
🔁 生命周期管理	统一管理编译、测试、打包、部署流程
📜 插件系统	可通过插件扩展（如编译器、测试、部署）

核心就是POM（Project Object Model），一个XML配置文件。然后maven工具读取这个xml，根据上面的配置进行处理。

maven有三个生命周期

clean生命周期: clean
           |
default生命周期: validate → compile → test → package → verify → install → deploy

           |
site生命周期:site→ site-deploy 生成文档部署文档

所以典型命令是：

mvn clean package

这个命令就是首先清理之前的构建，再进行新的打包。

三个周期中最重要的是default周期，命令如下：

阶段（Phase）	作用
compile	编译源码
test	编译并运行单元测试
package	打包（生成 JAR/WAR）
install	安装到本地仓库
deploy	部署到远程仓库

2 一些实际例子

2.1 Hello

代码结构：

helloworld/
├── pom.xml
└── src/
    └── main/
        └── java/
            └── com/example/
                └── App.java

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.example</groupId><artifactId>helloworld</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><name>HelloWorld</name><build><plugins><!-- 编译和运行入口 --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.11.0</version><configuration><source>17</source><target>17</target></configuration></plugin></plugins></build>
</project>

App.java

package com.example;public class App {public static void main(String[] args) {System.out.println("Hello, Maven!");}
}

编译打包命令是mvn package

从log可以看出，maven自动下载的内容真的非常多。

Hello, Maven!

2.2 添加第三方依赖（如 Gson）

在pom.xml中增加，并且指示编译成fat jar

<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/4.0.0http://maven.apache.org/xsd/maven-4.0.0.xsd"><modelVersion>4.0.0</modelVersion><groupId>com.example</groupId><artifactId>helloworld</artifactId><version>1.0-SNAPSHOT</version><packaging>jar</packaging><name>HelloWorld</name><dependencies><dependency><groupId>com.google.code.gson</groupId><artifactId>gson</artifactId><version>2.10.1</version></dependency></dependencies><build><plugins><!-- Java 编译器插件 --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-compiler-plugin</artifactId><version>3.11.0</version><configuration><source>17</source><target>17</target></configuration></plugin><!-- 打包为 fat jar --><plugin><groupId>org.apache.maven.plugins</groupId><artifactId>maven-shade-plugin</artifactId><version>3.5.0</version><executions><execution><phase>package</phase><goals><goal>shade</goal></goals><configuration><transformers><transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer"><mainClass>com.example.App</mainClass></transformer></transformers></configuration></execution></executions></plugin></plugins></build>
</project>

修改代码App.java

package com.example;
import com.google.gson.Gson;public class App {public static void main(String[] args) {Gson gson = new Gson();String json = gson.toJson(new int[]{1, 2, 3});System.out.println(json); // 输出：[1,2,3]}
}

之后编译时会自动下载新的依赖。

运行：

[1,2,3]

2.3 多POM

项目结构：

myproject/
├── pom.xml  <-- 父项目
├── module-a/
│   └── pom.xml
└── module-b/
    └── pom.xml
父pom.xml

<modules><module>module-a</module><module>module-b</module>
</modules>
