首先创建mvn工程

mvn archetype:generate

选择quickstart后增加maven-shade-plugin到pom.xml

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd">
  <modelVersion>4.0.0</modelVersion>

  <groupId>com.shenli</groupId>
  <artifactId>mvntestapp</artifactId>
  <version>1.0</version>
  <packaging>jar</packaging>

  <name>mvntestapp</name>
  <url>http://maven.apache.org</url>

  <properties>
    <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>
  </properties>

  <dependencies>
    <dependency>
      <groupId>junit</groupId>
      <artifactId>junit</artifactId>
      <version>4.7</version>
      <scope>test</scope>
    </dependency>
  </dependencies>

<build>
<plugins>
  <plugin>
	<groupId>org.apache.maven.plugins</groupId>
	<artifactId>maven-shade-plugin</artifactId>
	<version>1.2.1</version>
	<executions>
	  <execution>
		<phase>package</phase>
		<goals>
			<goal>shade</goal>
		</goals>
		<configuration>
			<transformers>
				<transformer implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
					<mainClass>com.shenli.mvn.app.App</mainClass>
				</transformer>
			</transformers>
		</configuration>
	  </execution>
	</executions>
   </plugin>
   </plugins>
   </build>
</project>

书写mainClass：

package com.shenli.mvn.app;

import java.util.logging.*;
import java.util.*;

/**
 * Hello world!
 *
 */
public class App 
{
    public static void main( String[] args )
    {
        System.out.println( "Hello World!" );
		LogManager lm = LogManager.getLogManager();
		Enumeration e = lm.getLoggerNames();
		while(e.hasMoreElements()){
			System.out.println(e.nextElement());
		}
		Logger log = lm.getLogger("global");
		log.log(Level.INFO,"====info====");
    }
}

使用mvn打包

mvn clean package

直接运行jar

java -jar target\mvntestapp-1.0.jar

输出如下：

Hello World!

global
