mac的使用

1.查看環境變量的命令：

vim ~/.bash_profile

2.查看包含隱藏文件的文件列表

ls -al

3.更改mvn路徑

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

source .bash_profile

而後執行mvn -version查看環境變量是否生效

➜  ~ mvn -version

4.執行mvn clean package命令

➜  springCloud mvn clean package

➜  springCloud

執行順序以下：

一、使用清理插件：maven-clean-plugin:2.5執行清理刪除已有target目錄（版本2.5）；

二、使用資源插件：maven-resources-plugin:2.6執行資源文件的處理（版本2.6）；

三、使用編譯插件：maven-compiler-plugin:3.1編譯全部源文件生成class文件至target\classes目錄下（版本3.1）；

四、使用資源插件：maven-resources-plugin:2.6執行測試資源文件的處理（版本2.6）；

五、使用編譯插件：maven-compiler-plugin:3.1編譯測試目錄下的全部源代碼（版本3.1）；

六、使用插件：maven-surefire-plugin:2.12運行測試用例（版本2.12）；

七、使用插件：maven-jar-plugin:2.4對編譯後生成的文件進行打包，包名稱默認爲：artifactId-version，好比本例生成的jar文件：springCloud-1.0-SNAPSHOT，包文件保存在target目錄下（這個生成的包不能在命令行中直接執行，由於咱們尚未入口類配置到Manifest資源配置文件中去，後續會闡述）。

備註：

無論是compile、package仍是install等前三個步驟都是必不可少的。
