Marven入门

Marven是Java自动编译、打包工具的工具类

1，安装

    Marven是绿色软件，下载解压后，把bin目录加入到Path环境变量即可

    在cmd命令行下输入下面命令测试配置是否正确

mvn -v

2，Java源码，配置文件建立

参照下面结构，建立文件夹。

└── src
    └── main
        └── java
            └── hello

在hello目录下建立Java文件，pom.xml文件

package hello;

public class HelloWorld {
    public static void main(String[] args) {
        Greeter greeter = new Greeter();
        System.out.println(greeter.sayHello());
    }
}

package hello;

public class Greeter {
    public String sayHello() {
        return "Hello world!";
    }
}

            </plugin>
        </plugins>
    </build>
