    </build>
</project>

2. Test.java

package cn.zno.commandline;

import java.lang.management.ManagementFactory;

public class Test {
    public static void main(String[] args) {
        System.out.println("VM arguments:" + ManagementFactory.getRuntimeMXBean().getInputArguments());
        System.out.println("Program arguments:");
        for (String arg : args) {
            System.out.println(arg);
        }
    }
}

打包

mvn install 

we will see an entry like this in the META-INF/MANIFEST.MF file of the resulting JAR:

Manifest-Version: 1.0
Build-Jdk: 1.7.0_15
Built-By: Administrator
Created-By: Apache Maven
Main-Class: cn.zno.commandline.Test
Archiver-Version: Plexus Archiver
