先下载maven安装包。
我下载的是apache-maven-3.6.1
解压后在本地添加环境变量。如下：

在cmd输入mvn -v查看是否生效。

接下来创建Maven项目。如图所示：



创建完项目，添加依赖和maven工程。如下：

其中settings.xml文件中修改如下：

在pom.xml文件添加下面内容：

<?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>Spack_demo</groupId>
    <artifactId>Spack_demo</artifactId>
    <version>1.0-SNAPSHOT</version>
    <packaging>jar</packaging>
//以下是添加的信息

下载完了后，如果在src不能创建package，就进行如下操作

这样就可以正常使用了。
