mac的使用

1.查看环境变量的命令：

vim ~/.bash_profile

2.查看包含隐藏文件的文件列表

ls -al

3.更改mvn路径

export M3_HOME=/Users/guanguan/apache-maven-3.3.9
export PATH=$PATH:$M3_HOME/bin

source .bash_profile

而后执行mvn -version查看环境变量是否生效

➜  ~ mvn -version

4.执行mvn clean package命令

➜  springCloud mvn clean package

➜  springCloud

执行顺序以下：

一、使用清理插件：maven-clean-plugin:2.5执行清理删除已有target目录（版本2.5）；

二、使用资源插件：maven-resources-plugin:2.6执行资源文件的处理（版本2.6）；

三、使用编译插件：maven-compiler-plugin:3.1编译全部源文件生成class文件至target\classes目录下（版本3.1）；

四、使用资源插件：maven-resources-plugin:2.6执行测试资源文件的处理（版本2.6）；

五、使用编译插件：maven-compiler-plugin:3.1编译测试目录下的全部源代码（版本3.1）；

六、使用插件：maven-surefire-plugin:2.12运行测试用例（版本2.12）；

七、使用插件：maven-jar-plugin:2.4对编译后生成的文件进行打包，包名称默认为：artifactId-version，好比本例生成的jar文件：springCloud-1.0-SNAPSHOT，包文件保存在target目录下（这个生成的包不能在命令行中直接执行，由于咱们尚未入口类配置到Manifest资源配置文件中去，后续会阐述）。

备注：

无论是compile、package仍是install等前三个步骤都是必不可少的。
