Maven打jar包时没有把pom.xml中的依赖打入jar包中，导致项目运行出错
问题
当在IDEA中写完项目，准备打包时，在右侧工具栏选中Maven—>项目名下的Lifecycle—>clean—>package一系列打包步骤时
已经完成了打包流程，打包的jar包会生成在项目下target目录里，当你在控制台执行jar包时(这里比如我打的jar包名为test1.jar)
就会报错如下，类无法加载异常和没有找到类错误COPY1

配置后好更新maven依赖后再次clean和package即可在target目录里多出一个jar包
其中标有jar-with-dependencies是打入pom.xml依赖的jar包
为标有jar-with-dependencies是没有依赖的jar包
