maven 常用命令

参考博客 ：https://www.cnblogs.com/wkrbky/p/6352188.html

maven用来管理项目，包括项目的创建、编译、打包、运行等。

他提供了一些命令来完成这些功能，配置环境变量后，可以到处运行这些命令，命令会根据当前目录下的pom文件描述，和setting文件描述，调用其他工具实现功能。

常用命令：

mvn compile        编译源代码，创建target目录，生成class文件。 我理解实际是调用jdk的编译程序，只是maven同时管理者项目的信息，告诉编译程序，源文件在哪里，编译后放在哪里。

mvn package    先编译源代码，再将项目打包成jar、war包。  执行后target目录中会多一个jar文件和其他相关文件。

mvn install        先执行package操作，再将包放到本地仓库中去。    因为maven知道本地仓库的地址是什么。

mvn clean         清除产生的项目，将某个项目的target目录删除，即删除class文件，只剩下源码文件夹。

 

其他命令：

mvn validate   验证工程是否正确，所有需要的资源是否可用

mvn test          运行测试，应该是执行测试方法，没验证。 

mvn deploy   上传到私服
