手动创建maven工程

创建目录结构

Demo.java内容为

package com.HX;

public class Demo {
    public void hello() {
        System.out.println("Hello maven");
    }
}
java

DemoTest.java内容为

package com.HX;

import org.junit.Test

public class DemoTest {
    @Test
    public void test(String[] args) {
        Demo d = new Demo();
        d.hello();
    }
}
java

pom.xml内容为

<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">
    <!--声明项目描述符遵循哪一个POM模型版本。模型本身的版本很少改变，虽然如此，但它仍然是必不可少的，这是为了当Maven引入了新的特性或者其他模型变更的时候，确保稳定性。-->
    <modelVersion>4.0.0</modelVersion>

    <groupId>com.HX</groupId> <!--公司或者组织的唯一标志，并且配置时生成的路径也是由此生成，如com.winner.trade，maven会将该项目打成的jar包放本地路径：/com/winner/trade-->
    <artifactId>maven-text</artifactId> <!--本项目的唯一ID，一个groupId下面可能多个项目，就是靠artifactId来区分的-->
    <version>1.0.0</version> <!--本项目目前所处的版本号-->

    <!--坐标表 (也就是依赖关系表)-->
    <dependencies> 
        <!--一个坐标-->
        <dependency>
            <groupId>junit</groupId> <!--依赖项的组织名-->
            <artifactId>junit</artifactId> <!--依赖项的子项目名-->
            <version>4.13</version> <!--依赖项的版本-->
        </dependency>
    </dependencies>
</project>
