java 开发语言 经验分享 ④【Maven】Maven的构建命令

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

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…）

D:\maven-workspace\spaceVedio\pro03-maven-parent>mvn clean

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）
