假设我有一个maven项目叫：hello-world

新建一个HelloWorld类：

package com.dylan.mvnbook.helloworld;

public class HelloWorld {
	public String sayHello() {
		return "Hello Maven";
	}
	
	public static void main(String[] args) {
		System.out.println(new HelloWorld().sayHello());

	}

}

修改后的pom.xml文件，添加：<build>节点内容：

<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.dylan.mvnbook</groupId>
	<artifactId>hello-world</artifactId>
	<version>0.0.1-SNAPSHOT</version>
	<packaging>jar</packaging>

	<name>hello-world</name>
	<url>http://maven.apache.org</url>

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

	<dependencies>
		<!-- https://mvnrepository.com/artifact/junit/junit -->
		<dependency>
			<groupId>junit</groupId>
			<artifactId>junit</artifactId>
			<version>4.12</version>
			<scope>test</scope>
		</dependency>

	</dependencies>

	<build>
		<plugins>
			<!-- 配置打包信息 -->
			<plugin>
				<groupId>org.apache.maven.plugins</groupId>
				<artifactId>maven-shade-plugin</artifactId>
				<version>2.4.1</version>
				<executions>
					<execution>
						<phase>package</phase>
						<goals>
							<goal>shade</goal>
						</goals>
						<configuration>
							<transformers>
								<transformer
									implementation="org.apache.maven.plugins.shade.resource.ManifestResourceTransformer">
									<mainClass>com.dylan.mvnbook.helloworld.HelloWorld</mainClass>
								</transformer>
							</transformers>
						</configuration>
					</execution>
				</executions>
			</plugin>
		</plugins>
	</build>
</project>

这样项目上右击执行：RunAs---maven install

找到打包好的jar文件并执行，就会去执行HelloWorld类中的main方法：
