Maven的构建命令

  • 一、注意
  • 二、🚀清理操作的命令
  • 三、🚀编译操作的命令
  • 四、🚀测试操作的命令
  • 五、🚀打包操作的命令
  • 六、🚀安装操作的命令

一、注意

运行 Maven 构建命令时，必须进入到含有 pom.xml文件的目录中。如果没有在 pom.xml 所在的目录运行 Maven 的构建命令，就会发生错误：The goal you specified requires a project to execute but there is no POM in this directory

在这里插入图片描述

二、🚀清理操作的命令

命令：

mvn clean

效果：

删除 target 目录

（代码为成功效果演示，可忽略…）

三、🚀编译操作的命令

命令 – 效果：

编译主程序的命令：mvn compile

编译测试程序的命令：mvn test-compile
  • 主体程序编译后的结果存放在target/classes目录下
  • 测试程序编译后的结果存放在target/test-classes目录下

四、🚀测试操作的命令

命令：

mvn test

效果：

对工程中 test目录 下的程序进行测试，测试的报告放在target/surefire-reports目录

五、🚀打包操作的命令

命令：

mvn package

效果：

执行命令的工程会被打包成 —— jar包，得到的jar包被存放在target目录中

六、🚀安装操作的命令

命令：

mvn intall

效果：

将本地构建过程中生成的 jar 包存入 Maven 本地仓库。

（代码为成功效果演示，可忽略… 示例的pro03-maven-parent工程是打包方式为pom的管理子工程的工程，其与其子工程生成的jar包就会被存放到本地仓库的指定路径中去）

被存放的 jar 包在 Maven 仓库中的路径是根据它的坐标生成的：

  • 某个工程坐标：
  cpm.haojin.maven
  pro04-maven-module
  1.0-SNAPSHOT
  • 生成的路径：
D:\maven-repository\com\haojin\maven\pro04-maven-module\1.0-SNAPSHOT\pro04-maven-module-1.0-SNAPSHOT.jar
