使用maven快速生成打包文件2

前面介绍了使用Maven打包基于SpringBoot开发的微服务，打出的JAR包包含所有的依赖，因此一般包比较大，可能会有几百M，但是有时候在调试阶段，经常需要更新程序，每更新一次就要上传几百M的JAR包，特别不方便，因此这里提供一种方法将依赖的JAR包统一放到lib目录中，这样打出的微服务包就很小了，更新起来也方便很多。先上pom.xml文件

        </execution>
    </executions>
</plugin>

maven-dependency-plugin插件将项目的依赖库复制到一个指定的目录中，指定的目录配置到outputDirectory即可。excludeScope表示将test的依赖排除掉，也可以在excludeArtifactIds中指定特定的依赖。
然后编译打包的时候，只需执行maven clean package即可。
