Maven 学习笔记 045 创建 Java Module

1. 创建 java 工程模块

父工程的 pom.xml 会自动出现 modules，打包方式自动改成 pom

<?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>com.atguigu.maven</groupId>
    <artifactId>pro01-maven-idea-parent</artifactId>
    <packaging>pom</packaging>
    <version>1.0-SNAPSHOT</version>
    <modules>
        <module>pro02-module-java</module>
    </modules>

    <properties>
        <maven.compiler.source>8</maven.compiler.source>
        <maven.compiler.target>8</maven.compiler.target>
        <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
    </properties>

</project>

2. 测试

pro02-module-java 增加 junit 依赖，添加完后手动导入一下，否则不能用

    <dependencies>
        <dependency>
            <groupId>junit</groupId>
            <artifactId>junit</artifactId>
            <version>4.13.2</version>
            <scope>test</scope>
        </dependency>
    </dependencies>

增加类

package com.atguigu.maven;

public class Hello {

    public void showMessage() {
        System.out.println("每一个不曾起舞的日子，都是对生命的辜负。");
    }

}

package com.atguigu.maven;

import org.junit.Test;

public class HelloTest {

    @Test
    public void testShowMessage() {
        new Hello().showMessage();
    }

}
