maven技术指南

1、标准maven工程的pom配置

<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/maven-v4_0_0.xsd">

  <groupId>com.caodejun.firstProject</groupId>
  <artifactId>mytest</artifactId>
  <packaging>jar</packaging>

  <name>mytest</name>
  <url>http://maven.apache.org</url>
  <parent>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-parent</artifactId>

</project>

2、maven常用命令和环境变量

mvn source:jar package 

mvn package 将源码打包成jar包，输出到target目录

mvn install 将jar包安装到本地仓库

mvn help:effective-pom

MAVEN_HOME=安装目录

mvn archetype:generate "-DgroupId=工程名称" "-DartifactId=项目名称" "-DarchetypeArtifactId=maven-archetype-quickstart" "-DinteractiveMode=false"

3、pom.xml 重要配置项

<repositories>
    <repository>
        <id>xlpaymaven</id>
        <name>xlpay maven</name>
        <url>maven私服url地址</url>
    </repository>
</repositories>
