環境：
ubuntu server 14.04.04 amd64 jdk1.8
1. 安裝：
http://www.jikexueyuan.com/course/571_4.html?ss=1下載、解壓、M2_HOME、PATH
mvn -version
2. 使用
http://www.jikexueyuan.com/course/maven/
2.1 java代碼
package com.jikexueyuan
public class App{
public static void main(String[] args){
System.out.println("Hello World!");
}
}
2.2 構建maven項目骨架
root@spark:~# mvn archetype:generate
結果：

Hello World!
成功。
參考：
eclipse maven：http://www.jikexueyuan.com/course/580_1.html
放自己的java代碼：比如MvnTest.java
內容如下：
package com.test;
/**
* Hello world!
*
*/
import java.util.Date;
public class MvnTest {
public static void main(String[] args) throws Exception {
Date d=new Date();
Class cl=d.getClass();
String name=cl.getName();
System.out.println(name);
String className="java.util.Date";
Class cl2=Class.forName(className);
System.out.println(cl2);
Class cl11=Date.class;
System.out.println(cl11);
Class cl12=int.class;
Class cl13=Double[].class;
System.out.println(cl12);
System.out.println(cl13);
}
}
root@spark:~/mvntest/src/main/java/com/test# ls
