maven - 包管理工具 - pom.xml

pom.xml位置

直接放在项目文件夹里
安装的包会在路径
C:\Users\用户名\.m2\repository

Jar包引入

<dependency>放在<dependencies>里

<dependency>
   <groupId>cn.missbe.web.search</groupId>
   <artifactId>resource-search</artifactId>
   <packaging>jar</packaging>
   <version>1.0-SNAPSHOT</version>
</dependency>

groupId:所需Jar包的项目名
artifactId:所需Jar包的模块名
version:所需Jar包的版本号

在IDEA里， pom.xml 右键 - Maven - Reload project - 可以自动下载需要的包
也在这里修改

pom.xml 坐标

<exclusions>
   <exclusion>
      <groupId>cn.missbe.web.search</groupId>
      <artifactId>resource-search</artifactId>
      <packaging>pom</packaging>
      <version>1.0-SNAPSHOT</version>
   </exclusion>
</exclusions>

pom.xml 描述项目包的文件
