1. maven下载

【官网】https://maven.apache.org/download.cgi

【其他版本】https://dlcdn.apache.org/maven/maven-3/

2. Idea 配置

1. 在Idea界面上关闭所有项目，全局配置：Ctrl + Alt + S 打开设置，搜索maven，配置如下

(1) maven home path: D:/Program Files/Java/apache-maven-3.9.1
(2）User seeting file:D:\Program Files\Java\apache-maven-3.9.1\conf\settings.xml
(3) Local repository :D:\Program Files\Java\repository

2. 配置运行程序Runner

-DarchetypeCatalog=internal

3. 配置Maven镜像

【阿里云效】https://developer.aliyun.com/mvn/guide

<mirror><id>aliyunmaven</id><mirrorOf>*</mirrorOf><name>阿里云公共仓库</name><url>https://maven.aliyun.com/repository/public</url>
</mirror>

4. 在Maven项目pom.xml中添加依赖

    <dependencies><dependency><groupId>org.apache.commons</groupId><artifactId>commons-lang3</artifactId><version>3.4</version></dependency></dependencies>

5. 创建jar包，更新pom，执行代码

右击Java -> New -> Package

输入package名称 -> 新建Java文件

点击idea右侧的 Maven图标-> 点击左上角刷新，更近pom中的依赖包

运行下面代码

package org.apache.jmeter.functions;/*** @author heartingme* @date 2023/1/10 4:25 下午* movingbrick*/import org.apache.commons.lang3.StringUtils;

}
