修改pom增加maven插件与build配置

<build>
    		<finalName>${project.artifactId}</finalName>
    		<plugins>
    			
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-jar-plugin</artifactId>
    				<configuration>
    					<archive>
    						<manifest>
    							<addClasspath>true</addClasspath>
    							
    							<classpathPrefix>lib/</classpathPrefix>
    						</manifest>
    					</archive>
    				</configuration>
    			</plugin>
    			<plugin>
    				<groupId>org.springframework.boot</groupId>
    				<artifactId>spring-boot-maven-plugin</artifactId>
    				<configuration>
    					<fork>true</fork> 
    					
    					<includeSystemScope>true</includeSystemScope>
    					<includes>
    						<include>
    							<groupId>nothing</groupId>
    							<artifactId>nothing</artifactId>
    						</include>
    					</includes>
    				</configuration>
    			</plugin>
    			
    			<plugin>
    				<groupId>org.apache.maven.plugins</groupId>
    				<artifactId>maven-dependency-plugin</artifactId>
    				<executions>
    					<execution>
    						<id>copy-dependencies</id>
    						<phase>prepare-package</phase>
    						<goals>
    							<goal>copy-dependencies</goal>
    						</goals>
    						<configuration>
    							<outputDirectory>${project.build.directory}/lib</outputDirectory>
    						</configuration>
    					</execution>
    				</executions>
    			</plugin>
    		</plugins>
    	</build>

执行maven打包

会出现lib目录与项目jar

解压jar查看 META-INF/MANIFEST.MF 文件

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQ2MTI4MQ_size_16_color_FFFFFF_t_70 1][]

jar包路径已经存入

只需要将 lib 文件夹上传到与项目同级目录下 即可运行项目jar包

重点: 如果引入了 <scope>system</scope> 包

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQ2MTI4MQ_size_16_color_FFFFFF_t_70 2][]

需要手动配置路径

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80MDQ2MTI4MQ_size_16_color_FFFFFF_t_70 3][]

否则打包后maven找不到包
