工具——Maven使用教学

回顾

Maven的安装配置

为什么称Maven是依赖管理工具？

先看一个示例：

新建一个maven项目，添加以下jar包依赖

<dependencies>
    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter</artifactId>
    </dependency>

    <dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-test</artifactId>
        <scope>test</scope>
    </dependency>
    <!-- https://mvnrepository.com/artifact/com.alipay.sdk/alipay-sdk-java -->
    <dependency>
        <groupId>com.alipay.sdk</groupId>
        <artifactId>alipay-sdk-java</artifactId>
        <version>4.38.23.ALL</version>
    </dependency>
</dependencies>
