maven多模块项目搭建

创建方式

创建父项目

#创建文件夹后，进入目录，执行以下命令
PS D:\demo> mvn archetype:generate
#将输出很多模板，供你选择，输入前面的数字，回车，进行选择
2129: remote -> io.quarkus:quarkus-amazon-lambda-rest-archetype (-)
2130: remote -> io.github.techacademy-curricula:daily-report-system-archetype (An archetype which contains a sample daily_report_system Webapp project.)
2131: remote -> com.bitofcode.archetype:jakartaee-microprofile (Jakarta EE with Eclipse MicroProfile project.)
2132: remote -> org.apache.maven.archetypes:maven-archetype-profiles (-)
#此时输入模板名称maven-archetype-quickstart
Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains): 17: maven-archetype-quickstart
#将会列出名为maven-archetype-quickstart的模板，此处一共有两个
Choose archetype:
1: remote -> org.apache.maven.archetypes:maven-archetype-quickstart (An archetype which contains a sample Maven project.)
2: remote -> com.github.ywchang:maven-archetype-quickstart (Provide up-to-date java quickstart archetype)
#选择要使用第几个
Choose a number or apply filter (format: [groupId:]artifactId, case sensitive contains): 1: 1
#选择使用的版本（该模板具有多个版本），我选择的是1.4版本，所以输入4回车
Choose org.apache.maven.archetypes:maven-archetype-quickstart version:
1: 1.0
2: 1.1
3: 1.3
4: 1.4
Choose a number: 4: 4
#开始下载模板

#输入groupId
Define value for property 'groupId': com.demo
#输入artifactId
Define value for property 'artifactId': multiDemo
#输入version,直接回车将使用默认值1.0-SNAPSHOT
Define value for property 'version' 1.0-SNAPSHOT: :
#输入package，直接回车，将使用groupId
Define value for property 'package' com.demo: :
#确认项目配置，回车即可完成创建父项目
Confirm properties configuration:
groupId: com.demo

创建子模块

在项目目录里，重复执行以上命令

目录结构

注意事项

1.子文件夹和module名要对应，否则无法正确识别，idea中无法解析为树状
2.子模块会继承父项目的build
3.插件的作用
4.引入其他模块
